   After upgrading to WordPress 3.0 from 2.9.2, I get this weird message as follows:

   Fatal error: Call to undefined function use_codepress() in /home/e2pcom/public_html/wp-content/themes/thesis_17/lib/admin/admin.php on line 42

   This message displays after I click on the Custom File Editor, thus, I do not have access to custom.css, layout.css and custom functions.php to make revisions to the code.

   Please help.

   Yours,

   Jae

   Deactivate all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).
