Disable Apache mod_rewrite Rules in any Subdirectory

Let’s say you have some .htaccess rewrite rules in place using Apache’s mod_rewrite. By default if the rewrite rules are located in the root directory, they will be applied to every subdirectory, as expected. But what if you need to disable the rewrite rules so that they do not affect some specific sub-directory or sub-folder? This super quick tutorial shows the easiest way to do it. Continue reading »

4 Ways to Make a WordPress Site Private Access Only

LOTR: Doors of Durin

Have you ever wanted to make a WordPress site private? So that only specific users are allowed access? For example, for my found-images site eChunks.com, I decided to require user login in order to access any content. So now for that site, public access is not allowed, and any posts, images, and all other content is available only to logged-in users. This tutorial explains four ways to make a WordPress site private or members only, so that only authenticated/trusted users […] Continue reading »

Code Snippets to Customize WordPress Sitemaps (Complete Guide)

Code Snippets for WP Sitemaps

By now most have heard about the WP Sitemaps feature introduced in WordPress version 5.5.

But for new WordPress sites going forward, having all the sitemap code in the WordPress core now means that new sites have the option of rolling with the default WordPress sitemaps, or use a dedicated plugin to do the job. This post is […] Continue reading »

[ Perishable Press Books (screenshot) ]

After six months of on-again, off-again hard work (and plenty of unexpected challenges), I am excited to launch the new Perishable Press Bookstore.

All the little .txt files you can put in the root directory of your website

The ones I know of: ads.txt humans.txt robots.txt security.txt This site makes use of robots.txt and humans.txt. I don’t need ads.txt because 3rd-party ads aren’t currently running on the site, and security.txt seems not necessary as the site’s contact form is easy enough for anyone to find. Continue reading »

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

[ Scooby Doo Intro ]

Recently I noticed a weird bug in my free WordPress security plugin, Banhammer. For some reason, I could not select any text on the page. Usually when you click and move the mouse cursor over some text, it becomes highlighted and displayed in some other color. But this wasn’t happening on the Banhammer settings screen. No matter which HTML/text I tried to select, it just wasn’t working. T’was a real mystery.. Continue reading »

PHP Code Not Displayed in Browser

[ Screenshot showing proper display of PHP code snippet ]

Recently a reader sent in a bug report about this post on bbPress. For some reason the PHP code snippets were not displaying properly in the browser. Basically, instead of looking neat and tidy as always, the code looked like a garbled mess of spaced-out nonsense. And by “spaced out” I don’t mean in a good way: there was literally like 100px of vertical space breaking up the jumbled lines of code. It was definitely a mess, so I began […] Continue reading »
