Hi, the best way to check is by disabling/deactivating HMWP plugin. If you are not able to login to site’s backend then you can rename “hide_my_wp” plugin folder to something else in /wp-content/plugins/ directory (using FTP or hosting ControlPanel).
If the issue still persists after renaming HMWP plugin folder then the issue is not related to HMWP.
Hi, it shall work with web server with FCGId. Can you please let us know what exactly is the issue your are having with HMWP plugin? And is the issue only when HMWP is active?
Also, generate debug report from HMWP start tab and post it here as private reply. Thanks!
