Hi Kaponte, 

Can you help me understand how you’re getting to the 400 error page? In the meantime, we’re gathering more internal information. 

I had a community member attempting to register their account via SSO to our back end systems. 

Kaponte,

We’ve created a ticket regarding this error page, as it is not a standard error page. The Dev team is investigating this further. At this time, you can not customize the error 400 page because it should not normally occur and is most likely related to the SSO set up. 

FWIW, I was able to set the title and text on of this now using the following

Title:

Module: Forum

Key: error.400.title

Body:

Module: Forum

Key: error.400

I found this after using SSO to create a new account, then on the “set username” page I waited 5-10 minutes, then I tried to submit it (probably a form token expired). Then I saw the error tags
