When I click on the Write link in the admin tab, the cursor shows busy while the file appears to load, but the screen does not change from the prior page (e.g. if it was on a Dashboard page, that's what it shows). No errors were given.
For themes.php, I'm getting the following error:
Fatal error: Call to a member function on a non-object in /www/htdocs/deirdreorg/blog/wp-includes/functions.php on line 1377
I've searched, but I don't see anything similar for either of these quirks.
