I have tried this but it still doesn't seem to work it just redirects me to my 404 error page (Another site of mine)

Would it be possible to install XOOPS again (The same version) and when installing it use the old database that way I don't loss any information?

If so where would I find instructions to follow? Also is their a way to double, double check that version I have as I believe I have version 2.2.3 but I thought it wouldn't hurt to double check.

Any help would be greatly appreciated.
