So last night i backed up my server and, im pretty sure thats what corrupted those core database files, but i restored the server to the backup and now it seems to be working fine.

I hope it doesnt do that agian.

I got a question for you expierienced joomla users tho:

If i have a ton of members on my site and say something like that happends agian that i cannot fix, how would i fix it and save all the registered members? If i reninstall would that whipe all the memebers? If so how to save them?
