Theme Error When Connecting Hosting

Hello,

I have installed the Blubrry PowerPress plugin and created a hosting account; however I am not able to link the two as there seems to be an error occurring within my theme files. When I click on any button or link within the plugin that brings up a window to login to blubrry, there is only a message: “The site is experiencing technical difficulties. Please check your site admin email inbox for instructions.”

The email states:

I’m a bit confused by where the error has occurred. I have very few plugins, and am only using the default editor for posts, etc.

Any help would he extremely appreciated!

Many thanks!

Warm Regards,
