AnyaR Thank you for the reply- sorry, I didn't see it until just now...
To answer your questions:
When did you first notice this issue occur? Around 2 weeks ago
And had you been making any changes to your site at this time? No, other than posting more content
Had you made any changes to any security settings within Cloudflare, or have there been any changes since? No, but the same day I noticed the issue (6 days ago) I tried creating a Cloudflare account and re-connecting Ezoic. It didn't help so I switched back to the previous setup
