WP 6.0 Fix Error: QTags is not defined
“Quick” post about an error that may occur with WordPress 6.0 (and possibly other versions). After updating to WordPress 6, the JavaScript Errors Notifier extension was showing a “QTags is not defined” error on sites where custom Quicktags are configured (via plugins or custom scripts). Because of the error, custom Quicktags were broken and not added to the editor toolbar. This quick post explains why the error is happening and how to fix it (easily). Continue reading »

Pimp Your 404: Presentation and Functionality

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 […] Continue reading »

Preventing the Unpredictable White Screen of Death for WordPress Sites with Multiple Themes
For the past several months and up until just recently, Perishable Press had been suffering from unpredictable episodes of the dreaded white screen of death. Although blank white screens happen to virtually all WordPress users now and then, certain configurations seem to trigger crashes more frequently than others. Here, I am referring to WordPress version 2.3. In this case, the unpredictable crashes, inconsistent errors, and general instability began several months ago after I had completed my WordPress theme restoration project. […] Continue reading »
Unexplained Crawl Behavior Involving Tagged Query Strings
I need your help! I am losing my mind trying to solve another baffling mystery. For the past three or four months, I have been recording many 404 Errors generated from msnbot, Yahoo-Slurp, and other spider crawls. These errors result from invalid requests for URLs containing query strings such as the following: https://example.com/press/page/2/?tag=spam https://example.com/press/page/3/?tag=code https://example.com/press/page/2/?tag=email https://example.com/press/page/2/?tag=xhtml https://example.com/press/page/4/?tag=notes https://example.com/press/page/2/?tag=flash https://example.com/press/page/2/?tag=links https://example.com/press/page/3/?tag=theme https://example.com/press/page/2/?tag=press Note: For these example URLs, I replaced my domain, perishablepress.com with the generic example.com. Turns out that listing the plain-text […] Continue reading »

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 »
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.
