Error 1101: Rendering error

Common cause

A Cloudflare Worker throws a runtime JavaScript exception.

Resolution:

Provide appropriate issues details to Cloudflare Support.

Unless this is your worker, you’d have to ask Siteground about this, as it’s most likely their SG Worker that’s not handling this correctly.
