Video

Hello, I've just switched over from Preachit! and still getting adjusted. I have Joomla 3.7 website, Sermon Speaker 5.6.2, and the default player is set for video. I do have JW Player 7 extension, but not using it. When I load an mp4 video sermon, 54M, it won't show on the site. I've tried several ways of doing this, and formats, but not luck so far. The error I'm getting is:

Fatal error: Cannot redeclare class getid3_exception in /home2/lcrsgv/public_html/components/com_sermonspeaker/id3/getid3/getid3.php on line 1840

If I could get a little direction I'd appreciate it. I set up our site 3 years ago and have gotten a lot better, but it was my first one and I'm about a 4 on a techie scale so be gentle.

Thanks in advance, Mic

That error means another extensions is including the GetID3 library and now conflicts with SermonSpeaker.
It's most likely a system or content plugin related to audio somehow. Disabling that plugin should solve the issue.
If you can tell me which plugin it is, I can have a closer look.
