You’ll need to go back to who ever you purchased that plugin from and ask them for support for this problem. The volunteers here don’t have access to the code of the plugin that you’ve purchaed, so we can’t trouble-shoot any issue like this. You’ve also paid for the vendors support, so thyey’ll be the ones to ask. Reply To: What this is causing thie fatal error?
