WordPress do_shortcode doesn't work. It returns text
The way to run shortcodes form PHP code in WordPress is "do_shortcode".
You plugin doesn't work with that.
echo do_shortcode('[jwplayer file="http://vid1-ams.smcdn.net/vod/_definst_/mp4:cms/lezentv/mp4/waltervandenbroeckHQ.mp4/playlist.m3u8"]
Working example for other shortcode:
echo do_shortcode( '[gallery]' );
I have seen earlier questions on this subject however these also don't work for me.
