Ok- I seriously need help with this one.

[THL]

So, I accidentally uninstalled the SEO 4 mod on an SMF forum (1.1.5) and I can't go anywhere on the site without getting Error 404 messages and whatnot. I can't even access my admin panel. So basically... How can this be reversed? Is there a way to tweak the urls so I can apply the mod again?

Upload the latest back up of your index.template.php file for whatever theme you were using.  If that doesn't work... upload the latest back up of your main forum folder's index.php file also.

Then once you are able to access your site again, figure out exactly which files were affected by you uninstalling that mod, and fix them manually.
