tcideas0, you can't simply change the plugin folder name to deactivate them. That will cause your plugins to be "missing" and if wordpress can't find /plugins/index.php it will confuse the admin panel. You need to be able to actually deactivate the plugins to get the plugin data disengaged. Also, ALL your themes need to be set to the default (2011) to see if it's a theme conflict.
I am not in any way soliciting credentials, esmi. He asked if I could look at it and I said if he is comfortable with that I am willing to help. I do this for a living and would never ask someone to turn their servers over to me, nor would I allow anyone to ever post login credentials or any other sort of contact info on a public forum.
I am still willing to try and help without being able to see code, but if he really doesn't understand how to get to theme files or deactivate things manually, he'll probably need someone to look on his behalf.
