Error while setting up custom pages


I am trying to add an Under Attack custom page to my domain but that’s what I get when I try to preview it:

The page do not have any HTML markup issues nor gives problems when you navigate to it with your browser. If I try to publish it directly I get the following error:

“Your custom page must be larger than 100 characters (Code: 1203)”

What can I do to fix this?


This appears to be the same issue.



Hmm how do I contact Cloudflare Support?


login to Cloudflare and then contact Cloudflare Support

There is a ‘Get more help’ button to contact support.


I managed to solve it!

You need to disable Under Attack mode before setting up a custom page for it.


Thank you for sharing the solution, the error message doesn’t help much there, but your solution will probably help others in the same situation :slight_smile:
