Same question here. I tried similar names and even went thru the functions.php file to see if I could find the custom-post-type name. Any ideas would be appreciated!
Thanks – I ran the repair and was still able to add tables, but still no luck creating tables from WP. Do you think reinstalling WP or reverting to an old DB backup may provide some insight?
Just figured out my problem. If you are having this issue, and you have WP-Commerce installed, there is a conflict. Disable WP-Commerce and it should work just fine for you.
Please post a compatibility workaround if you discover one.
