Warning Wrapper is Disabled in Server Config

Hi!

I really like this theme and I want to use it but there is a long error message displaying in the middle of my webpage that talkes about a wrapper being disabled in the server configuration and no suitable wrapper could be found.

Does anyone have any idea why I am seeing this error message? I am not very well versed in code so i’m not sure how to fix it or if I can.

Thanks for any help!!
