   I upgraded my site to WP 2.5.1 on Friday. Now, I can't blog at all! My visual edit is missing as is the HTML editor. The categories section says:
   Fatal error: Call to undefined function: wp_category_checklist() in /wordpress/wp-admin/edit-form-advanced.php on line 244

   I can't see the reason for these three items having issues.

   Sounds to me like the edit-form-advanced.php file could be corrupt. Did you upgrade by uploading all the WordPress files via FTP? Sometimes this isn't the most reliable way (even if it's the only method available - I know it is for me).

   I am, of course, assuming that the error message means that the error is with that file and not with the one where the function it's trying to call resides...

   I'd try re-uploading this file individually and overwriting the one that's there. See if that helps. If not, try uploading the whole wp-admin folder again, and if not *that* then the rest of the core files.

   wp_category_checklist() is defined in wp-admin/includes/template.php, so that file is missing. Best is to delete both wp-admin and wp-includes directories and upload fresh copies.

   Thanks to both of you...I hope that helps. Iain, I think my webhost allows me to upload via it's backend thingy (yes, I speak tech) so I'll try to do that.

   FM -- do you know which files were causing the problem, or did you just replace the two directories wholesale?

   Replacing wp-includes directories fixed it for us!
