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 »
Have you ever wanted to make a WordPress site private? So that only specific users are allowed access?

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 »

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 »

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.

![[ Call to undefined function ]](https://perishablepress.com/wp/wp-content/images/2019/fix-error-undefined.png)
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 »

The only downside is that, well, you’re relying on another plugin. And that’s fine for folks who just wanna “get ’er done”, although each active plugin requires additional maintenance and server resources. Continue reading »
Recently a reader named Chris asked, “how can we turn ON a plugin from the database?” He mentioned reading my previous article, Quickly Disable or Enable All WordPress Plugins via the Database, but for circumstantial slash technical reasons needed to do the opposite and enable a plugin directly via the WordPress database. I thought it was an interesting question that might actually be useful to discuss here at Perishable Press. Continue reading »
While working on the site’s 24th redesign, I ended up with about 10 code snippets that were awesome but ultimately not needed. So rather than just delete these tasty functions, I am posting them here for future reference. Who knows, during the next site update I may decide to implement or repurpose some of these techniques.
