Cannot delete threads?

Every time I try to delete a thread I receive the error:

Sorry, but you did not select any threads to perform inline moderation on, or your previous moderation session has expired (Automatically after 1 hour of inactivity). Please select some threads and try again.

Any ideas how I can fix this?

is it a fresh install or upgraded forum ? looks like theme is not compatible with MyBB 1.8

Visit your Admin Control Panel, then go to Templates & Style > Templates > Find Updated Templates. This will show you a list of all the templates that have changed during the upgrade.

You can either revert these templates to their default - meaning all the changes you've made to it will be removed - or you can see a Diff Report which will show you exactly what's changed. If you have a custom theme installed, it is probably best that you look at the Diff Report and apply the changes you need.

or you can install a compatible theme for MyBB 1.8 and use it

I tried switching back to the default theme, it still doesn't work. (Even though the 1.8 theme I installed was made for MyBB 1.8 & downloaded from the themes section here, it was called 1point8.

I upgraded from MyBB 1.6.14 to 1.8

Try running File verification process or see your updated templates to revert them back.
