Delete Shared/Saved Gutenberg Blocks

Been playing with WordPress new Gutenberg functionality. While exploring the new features, I created some Shared blocks via the “Convert to Shared Block” button. After another hour of playing with the Gutenberg API, there were a number of “orphaned” Shared blocks (just due to swapping out code snippets while testing). After some searching, I found it is possible to delete Shared blocks programmatically with JavaScript, but could not find any specific documentation or examples. So, I came up with an […] Continue reading »

Display bbPress Posts without a Plugin

WordPress .htaccess file

The WordPress core uses .htaccess for two things: Permalinks and Multisite. This means that .htaccess is only required if you have enabled either of these features. Otherwise, .htaccess is entirely optional for default WordPress installations. Beyond the WP core, many plugins also use the .htaccess file for custom directives involving rewrites, redirects, custom headers, file compression, and much more. In many cases, such plugins add their .htaccess rules to your .htaccess file automatically, behind the scenes. Continue reading »

Stop User Enumeration in WordPress

With a simple enumeration script, an attacker can scan your site and obtain a list of login names in a matter of seconds. Continue reading »
