Our site just went down. Users are receiving a Blocked because of IPS attack messages. I restored the site to a backup and it still persists. I check cloud flare and it seems to be a cache issue. I go into developer mode and the site works fine again.
I purged the cache and disabled developer mode but it stays broken.
I temporarily disabled cloud flare and it stayed broken.
I don’t really no where to turn if developer mode fixes it but disabling cloudflare does not.
That’s not a good sign. Another recent thread had a similar issue. This is your host’s security settings that need to be addressed. You’ll have to work with them to fix this. Especially if it happens when Cloudflare is disabled.
