Recently we developed an issue with Manage-Pages in the dashboard.
When you click the "pages" tab under "manage" in the dashboard, the page that displays has the main header with the visit site button, links in the top right hand corner, and the main content area is blank. Also, the "dashboard" link button that is usually in the top left corner is missing.
I replaced the wp_includes and wp_admin folders from back-up copies and that has allows intermittent use of the edit page in firefox and IE7. Sometimes it requires a few "refreshes" to get the page to display, other times you have to empty your cache or cookies.
It is happening on multiple computers of the different admins for the site on Mac and PC.
Everything was working fine up until 1/30/2009.
Anyone else having this issue?
