WordPress multisite just shows the code of video playlist
I set up a WordPress multisite network on a local server using XAMPP. Now I have two sites: the "main" one and the identical second one that is simply used as the multilangual version of the main site. I activated the JW player plugin for Wordpress for the whole site network. I created a video playlist on both sites with the same videos, parameters and settings. they are supposed to show up at the index page of each site. But unfortunately only the playlist on the main page works. The second website just shows the code as integraded in the post section of Wordpress ([jwplayer player="1" playlistid="261"]) and isn't "generating" the playlist.
