Granted I’m reading between the lines, but I think he did. It probably went away with no action on his part after the relevant Wix developer or system admin noticed their mistake. I’ve run into CORS errors a couple of times myself, though that was with HTTP functions.
Are you absolutely sure a CORS header that should definitely be present is absent? And this is Wix’s fault (as I say it does happen)? If it’s definitely a bug, you can try posting on this forum with [BUG] in the title or you can try your luck with support.
