An issue that’s come up as a result (I think) of removing the categorydiv from the listing form:
When the changed listing it put into the moderation cue, the category is no longer selected, and has to be set by the moderator before approving. My theory is that since the field is not being submitted as part of the change, it overwrites the category field in the database with nothing. This is not an issue with the other fields I’m removing, since we’re not using those, but I suppose the same thing is happening with them as well.
Instead of removing the categorydiv as above, I’ve hidden it using a little CSS in the admin header and tested, and the correct category is now displayed in the moderation cue, while it’s no longer displayed to users.
