After upgrading a CMS site to SP2 I get the message "This page is not available for the active language" above the edit window in the Editor pages.
The site is only available in one language, English, and apparently the site runs just fine judging on what the end users see.
Does anyone have any ideas regarding this?
I experienced the same problem upgrading from 5.2.375.7 to 5.2.375.236. Following the instructions here solved the problem.
