Youtube-Video don't show up in right size

Thank you DanielHunziker,

Could you please set the height and width value 100% and check again? 

Don't forget to delete all caches and do CTRL+F5 on the frontend. 

If it doesn't help please leave your forum URL to allow us to check it. 

Thanks for your reply.

I've already tried it before and tried it now again. With set to widht and hight 100% it looks like this:

I've deleted all caches (caches from my host, caches of wpforo, caches of browser), but unfortunately it doesn't work.

Here is the url:

Hi DanielHunziker,

Please navigate to Dashboard > Forums > Settings > Styles admin page, put this CSS code in "Custom CSS Code" textarea:

#wpforo-wrap .wpforo-post-content .wpf-video, #wpforo-wrap .wpforo-post-content .wpf-video iframe{
    max-width: 98%;
}

Then navigate to Dashboard > Forums > Settings > Addons > Embeds admin page set the static height value( e.g. 320px). 

ok, we'll check and back to you asap.
