Weird Bug with Highlight.js

Working on adding syntax highlighting to my code snippets here at Perishable Press. To do it, I use my free WordPress plugin Prismatic. Basically all the plugin does is load up either the Highlight.js scripts and styles, or it loads up the Prism.js scripts and styles. So I can rule out the plugin itself for this “weird” little bug. The issue is with Highlight.js specifically. Continue reading »

Case of the Invisible CSS ::selection

No matter which HTML/text I tried to select, it just wasn’t working. T’was a real mystery.. Continue reading »

How to Modify HTTP Headers in the WordPress Admin Area

WordPress provides the wp_headers filter hook and send_headers action hook to add and modify HTTP requests. For front-end pages, these are ideal hooks that should be used whenever possible. Unfortunately however neither hook works on all pages in the WordPress Admin Area. After some experimentation, I found an easy solution to modify HTTP headers on any/all pages in the Admin Area.

Vanilla JavaScript Smooth Scroll

While working on the site’s 24th redesign, my goal was to simplify the UI as much as possible. As much as I enjoy lots of cool effects, I wanted the new design to be as minimalist as possible. So that meant dropping a LOT of little bells and whistles that were included in the previous design. One feature that didn’t make the cut was smooth scrolling to internal anchor targets. Like when you click a link that takes you #somewhere […] Continue reading »

WordPress Error Fix: “Call to undefined function get_header()”

[ Call to undefined function ]

I’m seeing a big increase in bot attacks targeting theme files directly. First they get the URL to your theme directory. There are numerous ways for a bot to get this information. For example most themes include assets like CSS and JavaScript files, and the link includes the full URL. So then once they have the theme URL, bad bots will make direct requests for well-known theme template files, like index.php and header.php. Requesting template files directly may reveal possible […] Continue reading »
