Rate exceeded

I have migrated my news website to Replit but I'm waking up each day to a blank white page with the words “Rate exceeded” in the corner.

Replit’s AI said to investigate Supabase limits and add Cloudflare capture to my main registration form, of which I did and still no better.

Now it's saying it could be a Replit limit.

Has anyone else seen this and how did you solve it?

Cheers,
