The issue is flawed by the use of mega menu, this plug in makes the site very slow and also does not work as it should. Contact support and tell me that there is no way to fix it then copy and paste Kevin Sobo's response to roadrhemes support:
"Hi,
Now we don't have any solution because the plugin show menu correctly.
This plugin has many files so it take much time and we think you can use other cache plugin to make your site load faster."
Think twice before buying this item.
