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 »

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 »
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 »
I’ve been testing the beta for WordPress 5.7. So far no complaints but there is one weird thing it looks like they are adding, some weird 4-pixel width border that displays when you hover over any item(s) on the main WordPress menu. It’s even got a transition animation to make it feel extra wonky. Here is a screenshot for those who have not yet had the pleasure of experiencing the new stylez (look on the left-hand side of the menu, […] Continue reading »
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 »
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 »

Around the end of December 2019 and then now well into January of 2020, I’m seeing a massive spike in aggressive malicious scanning for uploads-related targets. In particular, there are massive numbers of requests for URL targets involving uploadify, plupload, and similar. Typical scans hitting upwards of 30K–50K requests per attack. Just relentless exploit scanning on steroids. Continue reading »
![[ POST Requests ]](https://perishablepress.com/wp/wp-content/images/2019/wordpress-post-requests.jpg)
I’ve written before about protecting against malicious POST requests using Apache/.htaccess. In this tutorial, we’ll look at how to modify GET and POST requests using PHP and some core WordPress functionality (with no .htaccess required). Normally you would want to manipulate URI requests at the server level, but that’s not always possible (like on shared hosting). So in those cases where you want to modify GET, POST, or other types of requests on a WordPress site, check out the following […] Continue reading »
![[ WordPress Image Sizes ]](https://perishablepress.com/wp/wp-content/images/2019/wordpress-media-image-sizes.png)
As you may know, WordPress creates numerous copies of all images uploaded via the WP Media Library. These additional images are generated in various sizes, depending on your settings and other factors. This may be totally fine in general, but if you are working with lots of images on your site, the extra files can really eat up your disk space. This can be wasteful, specially if your site does not make use of all the extra images. So to […] Continue reading »
