This is a site of a customer of mine, it is on a subdomain of his, so I built it on his hosting.
There was an issue with editing the WP site. They said there is an issue with Cloudflare - but gave no solution.
After several hours (and no one went back to me), I decided to move to my hosting. But the problem was the same. The first representative tried but wasn't able to solve but he kindly and quickly moved it to a higher level of support.
He got back to me in 10 minutes - and solved the issue.
