Wanted to try this plugin on my test page and this is the first time I have seen this error. I have successfully activated the plugin but when I try to access PHPLeague or Clubs page in the admin area, I get a blank white page with this text:
You don't have permission to access /wp-admin/admin.php on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
The admin.php persmissions aren`t the problem, I have also tried putting the following htaccess file in the admin folder:
... and again nothing changes.
What else can I try?
