The site was temporarily on a test subdomain (which foolishly wasn’t listed as the staging environment) when it was first spun up to test caching and some other issues. It’s now back to the same url. I’ve been through the trouble shooting tips and keep getting the blank page with no error messages.
There appear to be some typos in the trouble shooting tips as the url is miss formed with
& instead of a plain
& and references
x-addons-extensions whereas I think the correct reference is now
x-addons-home either way I can’t force any more specific error messages or updating.
I’ve amended the child theme as suggested but no effect. I’ve enabled debugging but no effect. The are no log entries suggesting other issues and the host can curl to other https sites. The host is running in a docker reverse proxy configuration behind cloudflare with W3 Total Cache but even disabling all caching doesn’t seem to have an impact.
Is there anything else I can do?
