But out of accordion it works fine. Then why php version don’t affect playlist out of accordion? Really there are no another suggestion? I can’t tell and they will not upgrade php version, because that is hosting server

That is not an option. In Accordion I can see that there are option create media list. And I have seen in another wordpress, that this is possible – http://www.bikerudraudze.lv/audioieraksti/bibeles-stundas/bibeles_stundas/

I have send in previous message access, please help. That is very important in that web page, that we can create such playlists.
Thanks
