ever since my wiki migrated to UCP, it seems like regular users are unable to post comments on pages. I've had lots of complaints from people that when commenting, a red box comes up that says "something went wrong. please try again later." at first I thought it was because of the whole migration thing, but it's been 3 weeks and it's still not working. however staff members are able to leave comments with no issue at all. does anyone know what's wrong/how to fix it?
