I already solved this problem, Thank you
Hello,
To resolve problems with Superfly menu, I followed the advice given in the previous post and deactivated and removed (via ftp) the superfly plug-in. Now I can install the X theme version but not activated (WP error) Because I purchased the full version Superfly menu, I contacted Looks Awesome , they advice to install and activate the Superfly X-theme version and then download and install the newest Version from Codecanyon Downloads page
