Can't seem to upload an IMDbPro image. The right side drop menu is blank...

I can't still seem to get this Add Image dropbox to appear normally. This is really the first time this has happened. I've never had this problem before. I tried this advice by disabling VPN and turning off Adblockers, but it's still not loading up. I see the circle loading, then blank white. Any other ideas, Col?

@FlikerTheatre​ Yes, there are a few things …  Please disable any ad blockers / VPNs and only then open a new private browsing / incognito window in your browser; login to IMDbPro in this window; try and add the photos. Sometimes vital parts of the IMDb pages can already have been incorrectly blocked by faulty ad blockers before you even reach the photo upload.Did you already try a completely different browser than your usual one as advised in the above help article? If so, which ones have you tried and on which system(s) have you tried this?If none of the above helps, please try adding the photos from the title page on https://www.imdb.com instead of via IMDbPro (see https://help.imdb.com/article/contribution/images-videos/imdb-image-faqs/G64MGN2G43F42PES for help).Please let us know what happens.
