A few days ago.. After an update to wp 3.0.. bye bye homepage and admin panel. Who knows why. Couldn’t login or reach wp-admin anymore (tried almost everything. Solutions suggested in forum, blog posts, official wordpress codex, tinkering with redirectrs and htaccess, checking folder/files permissions, disable plugins, upgrade form fantastico, new install form fantastico. Nothing worked.)
I think my original sin was the upgrade made with the wordpress own feature, instead of the cpanel/fantastico one.
Then I made a new fresh manual install of wp 3.0.1 (ftp+phpmyadmin, leaving fantastico alone), merged old files (plugins, themes, uploads…), copied relevant wp_ tables to the new database..
And here we are.
So, this is my suggestion if you are in the same trouble: a clean install in another directory, and then get you contents and plugin back.
Now I’m just wondering about switching to croogo..
