Login Issues - what to do
 

my vbulletin is 40kterra.com

I am seeing login issues, first you can login, but then you are sent back to the main forum home it shows that you aren't logged in.

Then when i click a thread i'm shown as logged in finally.

sounds like your computer is not saving cookies

To troubleshoot this, please remove any hacks and disable your plugins, then see if you still have this problem.
Note: To temporarily disable the plugin system, edit config.php and add this line right under <?php

define('DISABLE_HOOKS', true);

If so, reupload all the original vB non-image files (except install.php). Make sure you upload these in ASCII format and overwrite the ones on the server.

If your problem still exists, please create a new Style with no Parent set. Now browse the forum using this new style, do you still have the same problems? If you are troubleshooting login or guest issues, you will need to set this style as board default in the vBulletin Options.
