PHPMyAdmin alert box - missing value in the form - all usual fields are filled out?

Looks like a bug. Try going to Settings -> Features -> General tab and disable Ajax.

Then, try to create a new table and it won't use the popup.

I had this issue with the SQL form (where you can paste larger blocks of MySQL code). Not sure if it's a fluke, but I selected all of my input and then hit Go..and it worked.

Did you give it a table name. I had the same problem & I simply forgot to give it a table name...at the top.
