If you use Safari as your web-browser, you may have started having problems with videos not showing on the forum and it attempting a download which shows the error "Too many HTTP redirects".   Its a known problem with an update to Safari.   If you want to work around it for now, you can go to Safari Preferences and switch off the "Prevent cross-site tracking" feature.   You might want to turn it back on when you've finished on the this or other sites where you're experiencing the problem.
