I had the link in both the single file and the RTMP, but it doesn't seem to matter.I removed one and I still get the flash error.I had put it there to see if it would fix it.
I used JWPlayer in Joomla 1.5 version of this site, but I recently upgraded to 3.0 site and experiencing the error saying Flash is not installed, when it is.
Here is what it is saying in the source code:
<div style='display: none;'><div id='inline0' style='width:700px;height:500px;overflow:auto;'>
<div align="center">
<div id='jwplayer131'>You must have <a href="
get.adobe.com/flashplayer
">the Adobe Flash Player installed to view this player.
