Videos stuck on "loading ad"
Can't play online videos that are "powered by JW Player 7.11.1". They get stuck on a "Loading ad" screen that goes on forever.
Happens in Firefox, including in Safe Mode and with all plugins deactivated. Doesn't happen in IE.
No adblocker installed. And yes, I am in Germany, so the content should be accessible to me.
All other web video content that is not "powered by JW Player 7.11.1" (BBC, CNN, ABC, YouTube, ...) works fine.
Any help will be appreciated. Thank you!
