I accepted "Allow all cookies", and never got problems with YT videos, or other third party contents. I never blocked GraphiteGB before (never blocked anybody). Strangely GGB's posts (and only his posts) sometimes missing, but sometimes they are 100% OK. Probably those posts, which provided by a special external image hoster, that would be the key, thanks for the tip! However I cant find any options how to make an exception for those.nah, it's a cookies setting
if one gets prompted to chose cookie settings and dont allow all cookies (it's very tempting to chose "only necessary") these sort of things happens as in not seeing links to YT videos or to external image hosting services, etc
But now this is strongly offtopic.
