I logged into my website running WordPress 3.0, http://teddeh.org. The new 3.0 showed me that there was an update. I clicked the update tab, it said my theme; Arras Theme, needed an upgrade. I clicked upgrade. Then it said: "The page you are looking for does not exist" in the middle of the screen, but with all the backend from WordPress still there.
What's the problem?
My site is now, appearently, down for maintenance and has been for the last 10 minutes. No matter what i try, i get to the same page: "Briefly unavailable for scheduled maintenance. Check back in a minute."
What have you tried?
I have tried logging into my backend. I have tried clicking the back-button and change the theme.
Thanks for your help in advance!
RESOLVED: Trust the CMS. The update is now done, even though it took a lot more time than i thought. Anyone else getting this error: WAIT!
