I am still having trouble getting the Package Builder plugin to work correctly.
I have this redirect in my htaccess:
Redirect /updates/plg_xxxx_xxxx.xml /index.php?option=com_comprofiler&view=pluginclass&plugin=cbpackagebuilder&action=versions&func=joomla&id=1&format=raw
But I get the error: Could not open update site. If I try the URL directly in a browser i get an 401 Unauthorized - but where do I authorize this access ??? I really need a manual for this plugin.
