Plug-in is great but doesn't work with the YouTube plug-in called "Qtube" when it is on the same site. I used the CustomContent plug-in so that I could display my easypaypal plug-in as a module. So I added the plug-in to a new article and then displayed the customcontent module in the right panel of a page. Simple! Works fine except when I enable the QTube plug-in on another page. When Qtube is enabled, the easypaypal button appears and works but above it the page displays an error message related to my Qtube plug-in. There seems to be a conflict between the two plug-ins. The error message says:
Warning: Missing argument 3 for plgContentQTube::onPrepareContent() in /home/aumakua/www/www/plugins/content/qtube.php on line 23

This plug-in comes without any user documentation for the free download. Once installed, when you're in Joomla and you go to the plug-in parameters, there is almost no support there either; only very cryptic comments about what each parameter field means. There is a easy paypal forum, but it seems to be used by the plug-in developer and no-one else. It contains only a few posts about random features and not the typical problems/solutions you expect from a forum. I suggest you look elsewhere if you are a joomla beginner or even intermediate user.
