Problem with deleting vBlite.. UPDATE I thought it was fixed, problem is still there

[giper]

Hi guys...

I am brand new to vBulletin software so please take it easy on me.

I recently installed a vBulletin forum on my website, version 3.6.8. patch 2. Today I decided to install the vBLITE style that I found here.

Once I installed it and and chose it to be my new style (user override, not default style) I realized that it did not give me the option to change back to the default style. Not a big deal right? Except now I had no way of accessing the admin link!! Long story short.... I over reacted!!! I decided the only way to delete that style was to access "phpMyAdmin" which controls the MySQL database on my server and delete it from the database.

My problem:

My forum is acting very strange now. When someone tries to login it says "Thank you for loging in, "XXXX" but when it goes back to the main page it still shows that person as being logged out. And if that person tries to post a reply or start a new thread it prompts them to log in again and the process starts all over again.

Edit: It also appears that once I am logged in, it wont let me log out. It says "All cookies have been cleared" but it still shows me as logged in.

I'm able to sign into the site on 2 of my 4 computers. And it doesn't seem to matter which browser I use, I still get the same result. I've tried clearing cookies several times and that doesn't seem to make a difference.

I'm thinking that some of the code got left behind because of the way I deleted the style. I even tried......

Repair / Optimize Tables
Update Counters
Diagnostics

Under the maintenance tab in the AdminCP with no luck.

If anyone has any suggestion where to look for a possible fix it would be greatly appreciated.

Thanks in advance,
Brian.
