Critical Error

Good afternoon

I have recently migrated to a new host and server, and I am now experiencing issues both setting up feeds, and conducting a plugin systems check. For both I get the ‘There has been a critical error on this website. Please check your site admin email inbox for instructions.’ warning.

I have checked the logs and here are some examples of the errors displayed:

Any assistance in rectifying the issue would be much appreciated. I am using the elite version of the plugin.
