Help! I screwed up badly!
 

I have vBulletin version 3.5.3. I was working on removing a mod called vBChat 2.3. I removed all files pertaining to the mod. In doing so, it unfortunately changed the look of my forum.

I have a backup from a few months back where the templates are perfect. How can I dump the templates from a previous backup (where I backed up all the files, not the SQL tables)?

Backed up templates?
Like back up a skin..
if so you can just import the skin again and change what you messed up on =\

No, not the skin. I mean templates... like FORUMHOME, etc. Is there a way to restore templates from a backup of some kind? Are they stored within a file on the server, for instance? I'm in the dark about this right now.

If you backup the skin (1 XML FILE)
It stores all the templates
like FORUMHOME

Which file would that be and where is it located, please?

You can simply revert the template.

Templates get stored in a table in the database. If you don't have an SQL back-up then there is no way of getting your templates back. You can however, as Scribbller said, revert the template back to the vbulletin default.
