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 »

3 Ways to Exclude Content from WordPress Feeds

This may surprise you, but I post quite a bit of content that never appears in the site’s main feed. It is my impression that a vast majority of subscribers are interested in web/graphic-design and development-related topics, and are really much less interested (if at all) in the miscellaneous odds and ends that wind up in the ever-expanding Perishable Press database. In the past, the process of excluding content from the main feed typically involved changing the post-date to something […] Continue reading »

WordPress Hack: Multiple Email Recipients for Contact Coldform

In the current version of my custom contact-form WordPress plugin, Contact Coldform, there is no built-in method of sending emails to multiple addresses. The thought of adding such functionality had not occurred to me until recently, when a Coldform user asked about enabling it. After a bit of investigation, it turns out that integrating multiple-recipient functionality into Contact Coldform is as easy as it is practical. I will definitely be adding this feature to the next release of the Coldform, […] Continue reading »

WordPress Tip: Quick Hack to Block Spam for the Wordspew Shoutbox Chat Plugin

Recently, I reactivated an older version (1.16) of Jalenack’s Wordspew Shoutbox plugin for the Dead Letter Art Chat Forum. The DLa collective has been working on a new issue of their ‘zine and needed an easy online chat location for impromptu business dealz (ideas, planning, etc.). Almost immediately after reactivating the Shoutbox plugin, the chat forum was flooded with an endless wave of spam. The rate and volume of spam was so high as to render the forum utterly useless.

Blacklist Candidate Number 2008-05-31

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.. Just under the wire! Even so, this month’s official Blacklist-Candidate article may be the last monthly installment of the series. Although additional BC articles may appear in the future, it is unlikely that they will continue as a regular monthly feature.

Perishable Press 3G Blacklist

After much research and discussion, I have developed a concise, lightweight security strategy for Apache-powered websites. Prior to the development of this strategy, I relied on several extensive blacklists to protect my sites against malicious user agents and IP addresses. Over time, these mega-lists became unmanageable and ineffective. As increasing numbers of attacks hit my server, I began developing new techniques for defending against external threats. This work soon culminated in the release of a “next-generation” blacklist that works by […] Continue reading »

Universal www-Canonicalization via htaccess
