WordPress Tip: Careful with that Autosave, Eugene

After upgrading WordPress from version 2.0.5 to 2.3.3, I did some experimenting with the “post autosave” feature. The autosave feature uses some crafty ajax to automagically save your post every 2 minutes (120 seconds by default). Below the post-editing field, you will notice a line of text that displays the time of the most recent autosave, similar to the following: Surely, this relatively new feature provides an added layer of protection against lost work, but all is not perfect (yet) in the world of automatically saved content. Several months ago, I lost several hours of work because the autosave feature […] Read more »

Blacklist Candidate Number 2008-03-09

Welcome to the Perishable Press “Blacklist Candidate” series. In this post, we continue our new tradition of exposing, humiliating and banishing spammers, crackers and other worthless scumbags.. Imagine, if you will, an overly caffeinated Bob Barker, hunched over his favorite laptop, feverishly scanning his server access files. Like some underpaid factory worker pruning defective bobble heads from a Taiwanese assembly line, Bob rapidly identifies and isolates suspicious log entries with laser focus. Upon further investigation, affirmed spammers, scrapers and crackers are swiftly blacklisted from future access. For the most heinous offenders, we suddenly hear Rod Roddy’s guzzling voice echo throughout […] Read more »

Improve Site Performance by Increasing PHP Memory for WordPress

During the recent ASO server debacle, I raced frantically to restore functionality to Perishable Press. Along the way, one of the many tricks that I tried while trying to fix the dreaded “white screen of death” syndrome involved increasing the amount of PHP memory available to WordPress. This fix worked for me, but may not prove effective on every installation of WordPress. If you are unsure as to whether or not you need to increase your PHP memory, consult with your host concerning current available memory 1 and overall compatibility with a localized increase. Note that if your blog is running […] Read more »

WordPress Error Fix(?): Increase PHP Memory for cache.php

This trick isn’t guaranteed to prevent all WordPress-generated PHP memory errors, but it certainly seems to help reduce their overall occurrence. For some reason, after my host upgraded their servers to Apache 1.3.41, I began logging an extremely high number of fatal PHP “memory exhausted” errors resulting from the WordPress cache.php script. Here is an example of the countless errors that are generated: Read more »

Blacklist Candidate Number 2008-02-10

Welcome to the Perishable Press “Blacklist Candidate” series. In this post, we continue our new tradition of exposing, humiliating and banishing spammers, crackers and other worthless scumbags.. Scumbag number 2008-02-10, “COME ON DOWN!!” — you’re the next baboon to get banished from the site! Like many bloggers, I like to spend a little quality time each week examining my site’s error logs. The data contained in Apache, 404, and even PHP error logs is always enlightening. In addition to suspicious behavior, spam nonsense, and cracker mischief, this site frequently endures automated and even manual attacks targeting various XSS exploits, WordPress […] Read more »

Optimizing Google Analytics Performance

It has occurred to me lately that I no longer use Google Analytics for Perishable Press. Instead, I find myself keeping an eye on things using Mint almost exclusively. So, the question now is: do I continue serving the GA JavaScript to keep the profile active just in case I ever need the additional stats? I mean, Mint already does a great job at recording all of information I could ever need, so I no longer see the use for Google Analytics. I do wonder, however, if Google ranks GA-enabled sites a bit higher than non-GA sites. Hmmm.. it seems […] Read more »

Advanced PHP Error Handling via PHP

In my previous articles on PHP error handling, I explain the process whereby PHP error handling may be achieved using htaccess. Handling (logging, reporting) PHP errors via htaccess requires the following: Access/editing privileges for htaccess files A server running PHP via Apache, not CGI (e.g., phpSuExec) 1 Ability to edit/change permissions for files on your server If you are having trouble handling PHP errors using htaccess, these three items are the first things to check. If it turns out that you are unable to use htaccess to work with PHP errors, don’t despair — this article explains how to achieve the […] Read more »

Advanced PHP Error Handling via htaccess

In my previous article on logging PHP errors, How to Enable PHP Error Logging via htaccess, we observed three fundamental aspects of preventing, preserving, and protecting your site’s PHP errors: Prevent public display of PHP errors via htaccess # supress php errors php_flag display_startup_errors off php_flag display_errors off php_flag html_errors off php_value docref_root 0 php_value docref_ext 0 Preserve (log) your site’s PHP errors via htaccess # enable PHP error logging php_flag log_errors on php_value error_log /home/path/public_html/domain/PHP_errors.log Protect your site’s PHP error log via htaccess # prevent access to PHP error log <files PHP_errors.log> Order allow,deny Deny from all Satisfy All […] Read more »

Blacklist Candidate Number 2008-01-02

Come one, come all — today we officially begin a new series of posts here at Perishable Press: the public exposure, humiliation, and banishment of spammers, crackers, and other site attackers. Kicking things off for 2008: blacklist candidate number 2008-01-02! Every Wednesday, I take a little time to investigate my 404 error logs. In addition to spam, crack attacks, and other deliberate mischief, the 404 logs for Perishable Press contain errors due to missing resources, mistyped URLs, and the occasional bizarre or even suspicious behavior of the search-engine robots. Whenever possible, I attempt to resolve a majority of the “fixable” […] Read more »

Optimize WordPress: Pure Code Alternatives for 7 Unnecessary Plugins

In this article, my goal is to help you optimize WordPress by replacing a few common plugins with their correspondingly effective code equivalents. As we all know, WordPress can be a very resource-hungry piece of software, especially when running a million extraneous plugins. Often, many common plugins are designed to perform relatively simple tasks, such as redirect a feed, display a random image, or return a database value. For those of us comfortable with editing PHP and htaccess code, there is no need to bloat WordPress with additional plugins for the sake of a few routine tasks. For each of […] Read more »

How to Enable PHP Error Logging via htaccess

In this brief tutorial, I will show Apache users how to suppress PHP errors from visitors and enable PHP error logging via htaccess. Tracking your site’s PHP errors is an excellent way to manage and troubleshoot unexpected issues related to plugins and themes. Even better, monitoring PHP errors behind the scenes via private log is far better than trying to catch them as they appear at random visits. Thanks to the magical powers of htaccess, there is an easy way to implement this effective strategy. Hide PHP errors from visitors In our article, , we discuss a technique whereby PHP […] Read more »

A Dramatic Week Here at Perishable Press..

..And we’re back. After an insane week spent shopping for a new host, dealing with some Bad Behavior, and transferring Perishable Press to its new home on a virtual private server (VPS), everything is slowly falling back into place. Along the way, there have been some interesting challenges and many lessons learned. Here are a few of the highlights.. The tide may be turning for A Small Orange I am certainly not alone when I say that shopping for a new hosting provider and transferring websites is one of my least favorite aspects of web development. In my experience, switching […] Read more »

5 Easy Ways to Display Syntax Highlighted PHP Code

A great to way to share your PHP code with visitors is to display it directly in the browser with automatically generated syntax highlighting. Here is a screenshot showing an example of syntax-highlighted PHP code: Displaying your PHP scripts in syntax-highlighted form is an excellent way to share source code details directly with your readers. Rather than zipping the script and requiring users to download, unzip, and open the file in an editor, displaying your code directly saves you and your visitors time, effort, and hassle. Plus, in my opinion, looking at syntax-highlighted PHP code is a beautiful sight, day […] Read more »

Easily Adaptable WordPress Loop Templates

In this article, I present several heavily commented examples of WordPress loops. I have found that many readers appreciate these types of loop examples, as it helps them to understand how the loop works while enabling them to easily copy, paste, and adapt the code for their own purposes. In our first example, we examine a basic WordPress loop. When implemented, this loop will display “x” number of posts, where “x” represents the number specified via the WordPress Admin reading options panel. To use this code, simply copy & paste into your WordPress theme’s index.php file 1 and customize accordingly. Read more »

Fixing Mint after Switching Servers

After switching Perishable Press to its current home at A Small Orange, I began noticing an unusual problem with referrer data displayed in Mint. Specifically, the first item recorded in the XXX Strong Mint data panel — for both “Most Recent” and “Repeat” views — displayed several thousand hits for various site resources, all from the following IP address: zxw59eit.emirates.net.ae Apparently, this particular location represents an invalid “loopback address.” The requested resources appear valid, indicating typical traffic patterns, but the loopback address is not the actual referrer. This issue was preventing Mint from accurately recording mountains of vital referral […] Read more »
