I just upgraded to DMS version 1.1.5. The site still looks fine, but the drop and drag DMS editor when logged in gives a blank page. I tried to revert back to version 18.104.22.168, but the reinstall failed. I disabled a bunch of plugins, but that made no difference. I disabled all the chrome extensions that were giving JS errors, and that made no difference. I did see an error of something like pl.editor ver 1.1.5. Is that yours?
