Glad to hear that you like the plugin ??

After checking your site and the errors in the console this seems to be related to your server settings and max-length for allowed URLs having pretty low value. You can find more information about the error here.

Before changing this on your server or contacting your hosting provider to help you with this you can check if any security/caching plugin is causing this and deactivate them to see if that will make any difference. If it doesn’t help you can proceed with what I mentioned above.

Hope this helps ??
