new install. videos do not show on any page.

videos are being embedded from youtube and I can view them in admin. When I click on them, I can view them in the website, however, my albums block is empty, homepage, etc. Photos are showing up fine.

Check the albums privacy settings.

This may be related to a bug that I tried to explain to AlexT without success.   I think Boonex hard coded profile albums to set the privacy level to 3; which is public.  Now if you turn off the Public group in Admin, Dolphin still sets the privacy of profile albums to 3 even though privacy group 3 is disabled.  When this happens, the contents of the album are not viewable to the members because members have privacy group level 4 and since the public level 3 is disabled it prevents albums with level 3 from showing.  This is a bug; if the Public group is disabled in the Admin, Dolphin should default to setting profile albums to level 4, which is the member group, and thus the albums would show.

you got it GG

When you don't want public content, you don't want the Public Group enabled.  You could try to edit the album code to not set them to public but what I ended up doing was to just go into BxDolPrivacy.php and set the All group to value 4.
