Error while setting up custom pages

[annarita.rossi48]

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?

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
