Member directory will not display profile data

I have been using Ultimate Member since 2017, and we have recently launched a new website. I was surprised to find that I had to rebuild all of the UM forms etc, but I’ve done that and have meticulously checked that everything is identical to what it was on the old site. The only thing that is different about the new site is that it has a custom theme using the Gutenberg block editor. But the problem I have been struggling with for several weeks is that the member profile will not display in the directory. I have verified that the member database has been imported and we have data in all the fields. The member directory lists all the members, but when I try to edit a member’s record only the profile photo field is shown and nothing else. If I try to edit a record I get a message to say that the member has not entered any data. This is demonstrably untrue. I am actually a paying user as we have bought one of the extensions, the Mailchimp one, but I find that the official technical support is very unhelpful. They take several days to answer a question, and have not provided any solutions at all.
