We have an existing contribution page that had two profiles included (one for top of page, one for bottom). I'm not sure when this broke, but currently (v 5.10.3), the bottom profile now appears to NOT be selected, and when you first click on the "profiles" tab, you briefly see the following warning:
The selected profile is using a custom field which is not assigned to the "Membership" being configured.
The profile doesn't appear in the dropdown at all. I can see the fields if I preview or edit from this screen. If I choose another profile and save, the error does not show again, but the profile I need does not appear in the list, so I have no way of selecting it.
I'm not sure what this error means. How do you assign a custom field to a membership?
I have seen some posts here with similar-sounding errors, but they all seem to be related to issues that have long since been fixed.
Thanks for any guidance!
