PHP Fatal Errors, Critical Errors

Hi There,

I am experiencing a number of fatal PHP errors when evaluating your plugin for use with a client. Rather than typing up a list of each issue, I have recorded a short screen recording showing the issues and where they occur in the plugin:

Are you able to resolve?

Thanks
