I read what you two wrote and maybe you could help me...as my problem seems to be linked to authentification...
I've just upgraded from 2.0.4 to 2.7.1. I followed the instructions, but encountered a few problems. Anyway, I've solved most of them, but one : I can't edit pages.
I see the list, and underneath each title, I can only click to see the page. Whenever I create a new page, the status I get is "pending" and I'm not allowed to delete the page.
I can edit posts and approve/disaprove/erase comments, but I can't do anything with the pages.
I have no plugin currently running and I've "repopulated" each folder just in case.
It seems like I don't have that admin right anymore : how come? I'm the first and only admin !
If anyone could help... I'm getting seriously nervous (I need this for my job)
