Mobile Menu CK Light cannot be installed over Mobile Menu CK Pro

I had fix it by login an updated the extension, what has changed since my login ?
please enable again the login so that I can check

I didn't change anything

I don't mind giving you the login but what if I uninstall it completely including from the database, would that help? If so let me know what files to delete from the database.

Thanks!

you can try to uninstall but you may loose some settings.
there is nothing to delete from the database, you can uninstall it directly from the joomla extensions manager
