When I attempt to do delete multiple threads with logged in, it says

than enter my password but it says wrong password. I am using 3.7.1

If there is nothing to do, is there anyway to remove this:

I have been getting the same deal, but I log back in & the posts are deleted as requested, JPT.

How can I remove that ? Because it says my password is wrong...

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.
