In my admin panel I the menu links for the Database manager and the Nextgen gallery panels are wrong. All other menu links work.
When clicking any one of them, I get a page not found error.
For instance clicking the Gallery -> Gallery button I'm sent off to
while the correct (that I must paste into the browser to access the gallery admin) is
(I found that correct link in another WP installation I run.)
After pasting a correct link everything works until I have visited some other unfortunate admin panel.
I've tried to update the permalinks ('/%category%/%postname%/'), to triple-empty all cache and deactivate different plugins without luck.
Really grateful for any hints!
