New WordPress Plugin: Simple Login Notification
New WordPress plugin! Simple Login Notification does one thing and does it well: sends an email alert whenever an admin-level user logs in to your site. I use this plugin on all of my sites to keep an eye on any unauthorized activity. Not that I’m expecting any, but if it does happen I definitely want to know about it. The plugin size is only 4 KB (zipped) with virtually zero impact on performance or anything else. Win win win, […] Continue reading »
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 »
Replacement for JavaScript Errors Notifier (Chrome Extension)
Heads up about the JavaScript Errors Notifier extension for Google Chrome. Looks like it was removed from the Chrome store sometime last year. Not sure of the reason behind it, but can tell you that currently there are no suitable extensions to replace it. Kinda sucks because JavaScript Errors Notifier was one of my favorite “always on” extensions. It makes it easy to spot any JavaScript errors as you develop, design, or browse the Web. Fortunately there’s still a way […] Continue reading »
Enabling ModSecurity (Updated)
For years, I’ve not used ModSecurity for any of my own sites. Way back when I first tried ModSecurity, there were just too many false positives, so I stayed away from it, opting instead to develop my own fast Apache/.htaccess firewall. But my web host now is telling me that ModSecurity is required on all of their managed VPS plans. Continue reading »
Protect WordPress Media Files
This is an experimental technique that I am playing with. It’s the simplest possible way that I could think of to protect all files in the WordPress Media Library using only Apache/.htaccess. I’ve been testing the code on an image-heavy site and so far there are no issues. So I want to put the code out there for others to test and hopefully provide feedback if anything less than perfect. It’s a super simple method that prevents media files from […] Continue reading »
Roll Your Own Simple Password Manager on macOS
I’ve tried 1Password and Dashlane, and several other popular password managers for both Mac and PC. It always seems to be the same thing: things start off great and then go downhill from there. For example, I was loving 1Password, and then it locked me out of my password file/account. Likewise for a couple of years Dashlane was great, but then they started making drastic changes like moving from standalone app to browser extension Web-based UI. The confusion involved with […] Continue reading »
Cutting Floor Interview
When I spend time on something, like an interview, I like to know that it was actually published somewhere. Below is an interview that I completed for a web-hosting company that apparently now is missing in action. It covers how I got into web development, upcoming projects, web security, work flow, writing books, WordPress, and more.. Continue reading »

There are numerous ways to redirect requests using Apache’s mod_rewrite and mod_alias. This concise, friendly tutorial explains different ways to redirect a range of IP addresses, either IPv4 or IPv6. Continue reading »
Plugin Planet 2021 Redesign
Finally! Writing this post is the final step in the 2021 redesign of my WordPress plugins site, Plugin Planet. The site launched seven years ago in 2014. I think I spent a couple of months or so building the original site to the best of my ability. That first design stood the test of time, and honestly it would have been fine for another couple of years or more. But after seven years of changes, modifications, swapping out plugins, adding […] Continue reading »
CSS: Odd Bug with Colons and Combined Pseudo Elements
According to specification (and these helpful posts by Chris Coyier), CSS pseudo elements like ::before and ::after should be written with two preceding colons. It can be confusing because while pseudo elements are prefixed by two colons, like ::element, pseudo selectors (aka pseudo classes) are prefixed by only one, like :selector. So that’s the context for an odd little CSS bug.. Continue reading »
Vanilla JavaScript Toggle Divs Based on Radio Select Inputs
Working on the redesign of Plugin Planet, I needed a way to toggle between two divs based on which radio input is selected. This is useful for showing option-specific information conditionally, depending on the current active radio select field. This tutorial shows how to achieve it using vanilla JavaScript, so there is no need for including an entire library like jQuery. Very simple technique, requiring minimal amount of HTML markup and vanilla JavaScript. Continue reading »
Opt Out of Google FLOC for Site Visitors (One Line of Code)
Google has another new thing they are doing, called FLOC (Federated Learning of Cohorts). It’s used to — surprise — track user activity across websites. Opting out ideally is handled by the user, who can customize their browser settings to disable FLOC while surfing around the Web. Beyond configuring your browser to opt-out of FLOC, you can disable it on any website with a single line of code. Continue reading »
We Need a Favicon Standard
In the beginning favicons were very simple, 16 pixels square and done. The idea was for each website to have its own unique icon. So when people visited or bookmarked a website, it was easier to identify in the browser. Continue reading »
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 »
7G Firewall for Nginx
After several months of development, the official Nginx version of the 7G Firewall is out of beta and ready for public use. If you are not familiar with 7G Firewall, check out the documentation for the Apache/.htaccess version. The Nginx version of the 7G Firewall works the exact same way, so I won’t bother repeating everything here. The only difference is the implementation, how to set it up on an Nginx server, which is explained in this post. Continue reading »
4 Ways to Make a WordPress Site Private Access Only
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 »
