Background info: I’ve imported lots of posts with custom fields and different values.
When I go to the Add New Page page, the custom fields section is pre-populated with every combination of custom field->value (thousands of them). This makes for a very long page, and the Javascript takes long enough to execute that Firefox pops up the “unresponsive script” message.
I can delete the custom field entries one by one, but if PHP error reporting is on I get these Notices when trying to delete:
Notice: Trying to get property of non-object in …\wp-includes\capabilities.php on line 821

(That final “1” is in the error div as well.)
I’d really rather not click “delete” thousands of times for each page I want to add. Anyone know what’s going on here?
