Hello,
I have a similar problem.
I updated our Moodle from 1.7+ to 1.8.
Now, when I want to insert or update a resource or activity I only get a blank page.
After enabled debugging level to ALL, I get the following errors:
Update or Insert a label
php[6660]; PHP Warning: require_once(moodleform_mod.php) [<a href='function.require-once'>function.require-once</a>]: failed to open stream: No such file or directory in I:\Geral\Moodle8\mod\label\mod_form.php on line 2.

I've got the same problem with "Turn editing on" button. Additionally, a blank page appears when clicked on that button.
I'm using Moodle 1.8.2+ (2007021520).
This is what I get from debug mode:
Strict Standards: Creating default object from empty value in /var/www/moodle/app/theme/chameleon/config.php on line 9

Any help? Comments?

I guess I found a solution to the problem. In my case, it was non-standard “Book” module causing all that mess. After deleting it (using “Site Administration” block) everything went back to normal.
Problems with third party code during upgrade are also mentioned here:

Happy Moodling everyone!
