@BackwardsFeet @fathermaurer howdy Padre!
Happy to help. Is the error the "this block has encountered a critical error" type of error or the total white screen or death error page? I concur to check the server error log and the browser error console.
My guess is if it is the first error type, the server log will be clean but the browser console might reflect something.
Also happy to help setup a staging site and debug with you. Please let me know how I can help!
