WordPress 3.0: In the Update-Loop

After updating my WordPress installation to 3.0 I was stuck in the Update Loop. Every time I tried to access the admin interface WordPress would send me to the database update page where it then would say “No Update Required”. Turns out that WP-Cache was the culprit. After killing and restarting my memcache daemon I was finally able to complete the upgrade and manage WordPress again. What will take some more time to fix will be all the remaining problems like no longer working JavaScript functions.
