great tool but lacking a set of basic settings

Mijdar 10, 2023
Thanks for this great plugin. But the CSP settings are very difficult to choose. Can someone give us a basic setting for the CSP implentation ?if I follow the recomendations infosec mozilla for CSP I block many things on a basic WP site. for instance the /wp-admin/plugin-install.php page doesn't display the extension image anymore. thanks

Great addition to securing a site

Been using this for well over a year now. Works like a champ with custom themes, wide variety of plugins, and page builder themes. Of course, we keep all of these updated. The settings dashboard is very user-friendly. Much easier than adding these manually. Thank you!

Nice!

I use this plugin on many of my sites, and I have never encountered fatal error errors as in the comments. I am using PHP 8.0 and below. People who have problems should check if there are any other plugins that affect the htaccess file. This plugin takes care of the htaccess file. Talking about the plugin, the developer did a good job. All http header codes and descriptions are available. Respects!

No longer works with recent WP/PHP

Mijdar 24, 2022
Used this for years, it has been great but it needs updating for recent WP releases, and in particular for PHP 8.1 - there is some code that relied on earlier versions of PHP being forgiving or some common coding issues, which now breaks on an up to date system.

Good plugin.
