Continuing the discussion from Has the site been having slowness issues?:
This thread was recently mentioned in another topic where we discussed Discourse self-hosting.
Anyway, about this YouTube issue… could it possibly be related to our particular combination of the default Onebox settings (“Onebox” is the Discourse name for the link preview generator) with our “no image uploads allowed” policy (which is pretty rare among Discourse forums, and possibly a contributing factor to this issue)?
If a mod happens to see this post (and this hasn’t already been tried), what if we disabled YouTube previews altogether so that copying and pasting URLs will always work, albeit without the previews? At least it wouldn’t require manual URL editing every time…
We should be able to do that by adding youtube.com to the blocked onebox domains setting in the Discourse admin area.
Apologies if that’s already been attempted… I hadn’t looked at this thread until it was pointed out in the other one.
