Slow down; you move too fast.

I’m trying to post a sugestion to WordPress Ideas, but when I submit it, in the form on the bottom of this page (https://www.ads-software.com/ideas/) it returns this error:

Slow down; you move too fast.
Back to WordPress Ideas.

Since I couldn’t send the form, I saved my sugestion in this pastebin: https://pastebin.com/1fgpuqUx (Attachments slugs shouldn’t interfere with page slugs)

It happens when I try to comment on a sugestion as well.
