at first - thank you for providing us with this great plug-in! I tried mp3browser two days ago in a joomla 1.7 test environment but unfortunatley the plug-in is not working with the shop system "joomshopping".
It would be awesome to get mp3brower or commedia running in this shop component for joomla.
I am not developer of mp3browser. Dotcom Development made this plugin (the original version).
I made free modification of plugin, wich called MP3Browser New for Joomla 1.5. It has many new functions, also I corrected many errors in it.
But you right about Commedia component and plugin for Joomla 1.5+: I made it.
Now, tell me the address of Your site and version of Joomshopping, please, so I can see what is the problem there.
You need to make plugins working in category description or in good description?
