the JWplayer is not the same as the content plugin

what is the name of the file you installed?

the name of the plugin is plg_muscol_3.0.1_3.x System - Music Collection

this is the system plugin

it's not the content plugin, nor the jwplayer plugin...!

if you want to show albums inside an article you need to install the SHOWALBUM plugin

I can't find the SHOWALBUM plugin on this website but I found this article below.

Insert albums into articles
Music Collection comes with a Content Plugin that will allow you to easily insert album information inside an article. All you have to do is insert the tag {showalbum album_id} (no blankspaces, album_id being the id of the album to be displayed) in the place you want the album info to appear inside your article.

I have the content plugin installed but see the code and not the album front end !
Thanks for your help!

the plugin is called "Show Album in article"

you don't have the content plugin installed...

I don't see this plugin anywhere. Please send me link to the download page.
I don't have the show album in article plugin in my download area of joomlathat.com

Thanks

Thank you !
