The admin login does not seem to work and the FTP login seems to be missing the username.
The error messages look to be the old ones, prior to disabling Enhanced Categories. Which is good, and, expected.
When I get access, I will definitely debug and resolve the issue quickly. You should definitely be able to use the extension with no errors. I’m not sot sure why the error is happening for you since I can not replicate it, see no obvious reason for it and no one else has yet run into the issue.
