Important: Since version 2.0, this plugin now requires at least PHP 5.3. Please ensure you are running the latest available version of PHP on your server.

This plugin adds <a href="https://www.google.com/recaptcha/" rel="nofollow ugc">Google’s reCAPTCHA</a> to the BuddyPress registration page and WordPress login page to prevent bots from registering and keep your site free from spam registrations.
reCAPTCHA is “tough on bots, easy on humans”: while it is increbianle effective on preventing bots from registering, most of the time all the user needs to do to verify themselves is simply check a box.
After installing this plugin, you will need to <a href="https://www.google.com/recaptcha/admin" rel="nofollow ugc">register your site with Google</a> (requires a Google account) and enter the site key and secret key on the Settings > BuddyPress > Options admin menu. If you would prefer not to use Google’s service, there is an alternative security check method also available; see below;
Prior to version 2.0, a less effective security check method was used where the user needed to answer simple math sum before registering. This method is still available, and can be turned on on the Settings > BuddyPress > Options menu.

BuddyPress Security Check

Combat spam registrations for a BuddyPress-powered site using Google's reCAPTCHA

The KaTeX WordPress plugin enables you to use the fastest <a href="https://github.com/Khan/KaTeX" rel="nofollow ugc">TeX math typesetting engine</a> on your WordPress website. You can include TeX inside a <code>[katex]...[/katex]</code> shortcode or in a Gutenberg block. Either way the math will render beautifully on your website. When using Gutenberg blocks, the equations will render immediately inside your editor!
Equations in blocks or using the <code>[katex display=true]...[/katex]</code> shortcode will render on page in display mode–with bigger symbols–centered on their own line.
For compatibility with other LaTeX plugins, this plugin optionally supports <code>[latex]...[/latex]</code> shortcodes.
