We’re on EE5.4.0. For registration we use EEHarbor’s User addon. The registration page submission is handled via Ajax.

In case of an incorrect registration form submission (e.g. email address already registered), EE5.4.0 and/or User addon reponds with:

(1) 403 Forbidden status
(2) an html page that contains the submission errors

We then parse the html returned in the Ajax call and extract the errors from it and display them on the registration page.

When CSM is uninstalled (so that it does NOT interfere here), this all works just fine.

With CSM installed, which we bought and use for something else, this now breaks.

The reponse for an incorrect registration page submisison (e.g. email address already registered) is now:

(1) 200 response status, hence NOT an error response
(2) the html returned is simply the registration page, it does not contain the submission errors returned by EE5.4.0 and/or the User addon

My questions are:

(1) How can we configure CSM here to NOT interfere on this page ?

(2) if the above is not possible, then how do we need to configure the exp:user:register form and/or CSM to return the submission errors (in case of errors) ?

I’ve attached screenshot of our current CSM config, as you can see we only have one rule in there for a different page (and that one works, but is NOT Ajax driven).

this is the exp:user:register config:

{exp:user:register form:class="form-horizontal validate" form:id="register-form"}

What I tried:

(1) Added a rule in CSM for

(15) Registration Form (On Error)

but the result was still the same, we do not get the submission errors from CSM.

(2) Added return params to the exp:user:register form… we still do not get the registration errors.

Thanks.
