It has been awhile since I went in and updated one of the sites I manage.
When I go to the backend of my site (/administrator), it is simply a mask for the front-end.
So when I go to either of the below urls:
I see the content for
What I tried:
Disabled SEF urls in configuration.php.
Checked the redirects table in the db for weird admin redirects (there are none).
Checked .htaccess file obvious signs of hacking or malicious or really any redirects (there are none and I have just the stock .htaccess).
NOTE: If I disable the .htaccess file (rename via FTP), when I try to go to the admin page, I see a 404 error.
I think it has been hacked or I (or another user) have installed a security plug-in that hides the admin URL. Unfortunately, I cannot remember if I have done the latter. I checked for jsecure, not there. I do have admintools installed and tried disabling it to no avail.
I also tried to update to 3.5.1. I uploaded the update package, still cannot access the backend.
I should note the frontend works fine.
