My install of 2.0.3 was a new one via Fantastico on CPanel. I’m getting the same thing about not being able to delete posts.
I’ve tried the Tune-Up plugin, the Role Manager plugin, deleting cookies etc as suggested by monfresh, and nothing works – I *still* can’t delete my own admin posts.
There are no other users but me as Admin.
I haven’t tried the forced upgrade as I didn’t upgrade – am I right in thinking it’s only for upgrades?
Is there any other way around this problem? <tearing my hair out…>
