When I activate for the SuperFly plugin, I got the follow message:
Plugin could not be activated because it triggered a fatal error.
Parse error: syntax error, unexpected T_STRING, expecting T_CONSTANT_ENCAPSED_STRING or ‘(‘ in /homepages/37/d339474081/htdocs/wp-content/plugins/superfly-menu-80ohAN/main.php on line 14
Please try testing for a plugin conflict. You can do this by deactivating all third party plugins, and seeing if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
If it doesn’t help, please provide us with FTP credentials.
