Youtube videos black screen

[WeeeBen]

Yeah they were looking at it but couldn't find the issue initially so i'm apparently waiting until after the holidays for vb staff to look at it when they start working again.

Here's my theory, at one stage the video button in the advanced tab wouldn't work.
So instead of putting up a video via the video button, you can add a video using the "Post Link" paperclip.

So members alternated between using the video button and the post link button.

Now if I go to edit one of the posts with video and try and delete the video it doesn't allow that, I need to insert a valid url for it to work.
So I can't delete a url unless I add another url. it says, "error please enter a valid url".

Now when I click edit to edit a post with video it looks like this..



Can you see the blue box top left corner? hovering over it says "Post a Video"
but it doesn't work, it's just a picture, not a button.

The post below, I added the video using the video button in advanced editor.
click edit post and it looks like this..



as you can see it does not have the blue box on the top left, and I can delete the video and replace with text no problem.

So I think there was a conflict between the two possibilities of adding a video, one via video button, the other via url button.
so now no matter which version I upgrade to the error is like built in.

I'm thinking maybe the only way to fix it is to delete all posts with video's completely.
from that point it might fix itself?
