 * Hello,
 * Using latest free version of SecuPress.
 * Seems fine but after few days (not sure what happened today, I just de-activated/
   re-activated the plugin).
 * The rules added to be htaccess started to block and generate a 403 for the style/
   script files of WordPress in the backend.
   I deleted the rules (as well as other
   rules SecuPress n the htaccess) deactivated and deleted the plugin.
 * Sorry, through the time, it generates too many issues. I quiet reluctant to use
   it from now.
 * Best regards
 * Thibaut

 * Hello,
 * I think you’re talking about the CONCATENATE_SCRIPTS module, this will set this
   constant to TRUE and block load-scripts.php & load-styles.php URLs to be loaded
   to prevent possible DDoS.
 * You may have encounter a cache issue, or only the URLs were blocked and CONCATENATE_SCRIPTS
   was remove/commented. Because with the 2 things, everything works fine, only 
   1 and it’s not effective or only the other one and you have 403 en css, so the
   admin area seems broken.
 * You should test it again since it’s just a cache or constant issue. SecuPress
   will still secure your website like noone.
 * Thanks
