WordPress Plugin: Dashboard Widgets Suite

1 Plugin. 9 Widgets. Awesome Dashboard. Over the years, I’ve assembled a collection of Dashboard widgets that I use frequently on various sites. I find the WordPress Dashboard to be a convenient location for posting notes, viewing debug and error logs, and displaying social media icons, RSS feeds, and other useful information. I find these widgets essential, but I was spending way too much time installing and managing them on all of my sites. To help streamline workflow and boost productivity, I decided to bundle together my favorite Dashboard widgets into a single, easy-to-manage plugin. So today I’m pleased to […] Read more »

What Chrome Predictive URLs Look Like on the Server

Awhile ago, I was confused by repetitive 404 “Not Found” errors in my server logs. The 404 requests look like someone is typing out various words, a few letters at a time. This post shows what these weird 404s look like from the server’s perspective, and then goes on to explain why they happen and why there is no practical way of preventing them. Read more »

Analyzing Weird 404 Search Engine Requests

Lately I’ve been getting a significant number of really weird 404 requests for one of my sites. At first I ignored them. Then upon closer inspection, I realized that the requests were reporting user agents like Googlebot, Bingbot, and other top search engines. So there was cause for concern. You don’t want legitimate search engines tripping over endless 404 requests that are completely unrelated to your site content. That gets into “negative SEO” territory, and should be investigated and resolved asap. This article explains what I was dealing with, how I investigated, and what I did to resolve the issue.

Best Practices for Error Monitoring

Given my propensity to discuss matters involving error log data (e.g., monitoring malicious behavior, setting up error logs, and creating extensive blacklists), I am often asked about the best way to go about monitoring 404 and other types of server errors. While I consider myself to be a novice in this arena (there are far brighter people with much greater experience), I do spend a lot of time digging through log entries and analyzing data. So, when asked recently about my error monitoring practices, I decided to share my response here at Perishable Press, and hopefully get some good feedback […] Read more »

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 “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.. 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 »

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 »

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.

Roll Your Own SEO Log

Search engine optimization (SEO) is the business of every serious webmaster. The process of optimizing a website for the search engines involves much more than properly constructed document headers and anchor tags. Websites are like trees: their roots are the growing collection of content presented through the branching universe of the World Wide Web. Or something. The point is that optimizing a website requires nurturing the site itself while also ensuring proper exposure to the requisite elements of the internet. Read more »
