HiI have to manually upgrade from v2.2 to v2.3, because some problems I'm having like* files uploaded are automatically renamed to .txt* when trying to delete an attachtment, get blank page* still see v2.2 after upgrading "successfully" (theoretically)So- which mysql tables should I keep?- which folders should I backup on ftp?I would like at least to keep my users and categories with its articles... they are lot and must solve these problems asapThanks

I would like to know this process as well, since I keep getting an error when trying to upgrade.

Thanks Enrique, but I don't think my issue is a mime-type problem. I have other sites on this server and this is the only one that shows this issue upon upgrading. Other than that, it has run flawlessly.
