I just purchased s2 Member Pro (V 170722) plugin and installed it automatically via wordpress and the zip file. Installation seemed to go ok. Now I am am unable to open the installed plugin from the DASHBOARD to activate pro with mi licence. I get a ERROR 504 - GATEWAY TIMEOUT when trying to open INSTALLED PLUGINS. I can open the the plugin.php file but am not sure what I am looking for. Any help appreciated.
