I upgraded to the beta on Tuesday -- although I was careless about a couple of things and ended up having to recreate my wp-config file and create a new MySQL user. I got things up and running, and it all works fine, with one exception. When I try to use the selected categories-to-tags importer, I get the following fatal error, by itself on a blank page:
Fatal error: Call to undefined function: register_importer() in /home/lakeneu/public_html/wp-admin/import/wp-cat2tag.php on line 213
If I try clicking on the "import" selection from the dashboard, I get the exact same error message, although this time it's on a styled dashboard page.
I don't know if this is a bug, or something that I did when I upgraded, or just the result of some file in my directory that doesn't have the proper read-write access, or what have you. Does anyone have any suggestions?
