Blacklist Candidate Number 2008-04-27

[ Photo: Bob Barker Snarls at Rod Roddy ]

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.. Since the implementation of my 2G Blacklist, I have enjoyed a significant decrease in the overall number and variety of site attacks. In fact, I had to time-travel back to March 1st just to find a candidate worthy of this month’s blacklist spotlight. I felt like Rod Roddy looking over the Price-is-Right audience […] Continue reading »

How to Block Proxy Servers via htaccess

Not too long ago, a reader going by the name of bjarbj78 asked about how to block proxy servers from accessing her website. Apparently, bjarbj78 had taken the time to compile a proxy blacklist of over 9,000 domains, only to discover afterwards that the formulated htaccess blacklisting strategy didn’t work as expected. Here is the ineffective htaccess directive that was used: Deny from proxydomain.com proxydomain2.com Blacklisting proxy servers by blocking individual domains seems like a futile exercise. Although there are […] Continue reading »

Three Unsolved WordPress Mysteries

After several years of using WordPress, I have at least three unanswered questions: What’s up with the WordPress PHP Memory Error? Why do certain phrases trigger 403 “Forbidden” errors when saving or publishing posts? What happened to the Plugin Pages in the WordPress Codex? Let’s have a look at each one of these baffling mysteries.. Continue reading »

Redirect WordPress Feeds to Feedburner via htaccess (Redux)

In a previous article, I explain how to redirect your WordPress feeds to Feedburner. Redirecting your WordPress feeds to Feedburner enables you to take advantage of their many freely provided, highly useful tracking and statistical services. Although there are a few important things to consider before optimizing your feeds and switching to Feedburner, many WordPress users redirect their blog’s two main feeds — “main content” and “all comments” — using either a plugin or directly via htaccess. Here is the […] Continue reading »

How to Display Your Twitter Posts on Your WordPress Blog

[ Screenshot: Perishable Tweets Displayed at Perishable Press ]

Alright, time for another “How’d-you-do-that-thing-on-your-site?” post. This question comes from the one and only Mr. Graham of ImJustCreative.com. In a recent email, Graham literally begged me to share my “secret recipe” for displaying my latest Twitter Tweets (wow, did I actually just say that?) right here on Perishable Press: …Would be really really decent of you if you could let me know how to do it? Pretty please? How do you call the last twitter feed, what commands do you […] Continue reading »

Custom HTTP Errors via htaccess

We all know how important it is to deliver sensible, helpful 404 error pages to our visitors. There are many ways of achieving this functionality, including the well-known htaccess trick used to locally redirect users to custom error pages: # htaccess custom error pages ErrorDocument 400 /errors/400.html ErrorDocument 401 /errors/401.html ErrorDocument 403 /errors/403.html ErrorDocument 404 /errors/404.html ErrorDocument 500 /errors/500.html ..and so on. These directives basically tell Apache to deliver the designated documents for their associated error types. Many webmasters and […] Continue reading »

WordPress Tip: Careful with that Autosave, Eugene

[ Screenshot: WordPress Autosave Message (Saved at 2:34:02.) ]

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: Continue reading »

WordPress Tip: Remove Spam from the Comment Subscription Manager

[ Image: Jonny Quest (Inverted) ]

After investigating some unusual 404 errors the other day, I found myself digging through the WordPress Admin Area trying to locate the “Subscribe to Comments” options panel. As it turns out, administrative options for the Subscribe to Comments plugin are split into two different areas. First, the S2C plugin provides configuration options under the WordPress General Settings > “Subscribe to Comments”, which enables users to tweak everything from subscription messages to custom CSS styles. New to me was the other […] Continue reading »

What is My WordPress Feed URL?

[ WordPress RSS Feed ]

For future reference, this article covers each of the many ways to access your WordPress-generated feeds1. Several different URL formats are available for the various types of WordPress feeds — posts, comments, and categories — for both permalink and default URL structures. For each example, replace “http://example.com/” with the URL of your blog. Note: even though your blog’s main feed is accessible through many different URLs, there are clear benefits to using a single, consistent feed URL throughout your site. […] Continue reading »

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 […] Continue reading »

WordPress Discussion Management: Enable or Disable Comments and Pingbacks via SQL

Continuing my quest to stop comment spam without using plugins, I have decided to disable comments on “old” posts. In my experience, over 90% of comment, trackback and pingback spam occurs on posts that have been online for over a month or so, just long enough to be indexed by the search engines and picked up by spammers. Especially for older posts that have managed to acquire a little page rank, the frequency of spam attempts is far greater than […] Continue reading »

Quickly Disable or Enable All WordPress Plugins via the Database

[ The Flash ]

Recently, while dealing with the dreaded white screen of death, I found myself unable to login to the WordPress Admin area to manually disable all of the plugins used here at Perishable Press. In the past, I have dealt with this situation by simply deleting all plugin files from the server, however this time, time was of the essence — I had only a few minutes with which to troubleshoot, diagnose, and ultimately resolve the deadly white-screen syndrome. Fortunately, after […] Continue reading »

WordPress Plugins: Transfer Autometa Data to All in One SEO

During my last redesign and site overhaul, I finally made the leap from WP 2.0 to 2.3. In the process of synchronizing data and removing unecessary plugins, I managed to replace several keyword- and meta-related plugins with the incredible All in One SEO Pack (AiOSEO). One of the plugins replaced by AiOSEO is Autometa, an otherwise very useful meta-keywords management tool. With AiOSEO installed, there is no need for Autometa. Over the course of a year or so, Autometa had […] Continue reading »

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.. 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 […] Continue reading »

6 Ways to Customize WordPress Post Order

[ Graphic: Inverted Triangular Fractal ]

Recently, reader Luke Knowles asked how to customize the sort order of his posts in WordPress. Looking into a solution to this question proved quite enlightening. Within moments I was able to discern 4 methods for modifying post order, and then several days later I discovered 2 additional custom sorting techniques. After updating the reply to Luke’s comment, it seemed like some good information that other WordPressers may find useful. So, here are six ways to customize the sort order […] Continue reading »
