we checked it and in fact there is a problem as soon you rename the main menu from “main” to i.e. “my menu”. Fastest way to solve the problem is to rename the menu to “main”, but we made already an update to fix the problem.
New version is 1.02 and it’s available in your account. The only change we made in the file “custom.js.php” in the folder “7league/script/”, just in case you don’t want to update the complete theme.
