We use Vimeo videos with a private link which apparently is different than the embed code allows so we are getting this error above every video using ARVE with the new update to v9:

ARVE Error: src mismatch
url: https://vimeo.com/463810979/ec418581d2
src in: https://player.vimeo.com/video/463810979?byline=0&badge=0&portrait=0&title=0
src gen: https://player.vimeo.com/video/463810979?dnt=1

The link above to the page is on a dev server that is firewalled (but happened on our live corporate site until I rolled it back). I will have to whitelist your IP for you to inspect and can give admin login if necessary.

Removing the second (private number) does make it work. But we have hundreds of them and it worked fine before. It’d be preferable to not have this showing.
