De.scription and Message
Suddenly, when performing a couple of tasks in the ACP, I get a 404 - page not found error. For instance, sever users do not get the email to activate their account as it goes in their spam folder. So, I will go into the ACP and activate it for them manually and have them just log in. Now I get a 404 page not found error when I do this (ACP/User Admin/Inactive Users).
I also now get this error when I attempt to add a bot in the Bots Management section (when I click on add).
Both of these functions were working at around 2:00am this morning. No changes or modifications have been made to the system at all.
I could see in the Bots Management section that clicking on the ADD option was making a call to the /admin/admin_bots.php file. I checked and that file is there. That is as far as my troubleshooting ability goes.
Any suggestions on what might be causing this and how to correct it?
Thanks!
