I found another topic about this here but after I did all it said I didnt manage to solve the problem. First I had instlled 2.0 wordpress ... i have upgraded and it worked just fine.. everything was perfect..but i've made some mistakes...with the db..and i didnt had a backup.
So i had to reinstall. I use plesk ... so i've installed 2.0 again ....and now..even if i dont upgrade it sais i dont have permisions. After i force-upgrade ... i have some options.. (to view my admin profile ..and edit it) ..but i dont have any other options. Even if I upgrade (withoud force-upgrade|) .. to 2.3 I still have the same problem. I've tried this like 3 times... same thing.
i dont know what to do :( ...can anybody help me?
