Just recently users are getting warning of ossible danger on my Xenforo cloud site. Is this SSL and do I have to use SSLmate or is it part of the cloud?
Thanks.
you would need to look into how to get out of google safe browsing blacklist i guess. google search console should have information about this based on this support document:
This page is for people who own a website that is blocked by Google or Chrome browsers with a visible notification. Getting started Do you own the website?
google transparency report does say that the warning could appear only on affected pages: Unsafe content might only appear on some pages of a website. Check the URL of the specific directory or webpage you want to visit for more detailed safety info.
google search console is probably the place to check for affected pages. it's possible there are spammy content that tries to phish visitors.
