If I use a menu item to go to my Customer File Upload page, it picks up the parameters (profile id or group id) which I set as detailed in the help. It goes to the page no problem.
e.g.
http://www.website.com/index.php?option ... &Itemid=70
If I use Joomla Module type mod_login, select Login Redirection Page and select the menu item as above, it does not pick up the parameters.
It just tries to go to the page
e.g.
http://www.website.com/index.php?option ... h_uploader
Therefore, it gives the message "You have not specified the parameter for a profile or group id in the 'Menu Manager' or for your plugin. Please enter a valid id there."
This may be why some people get this message. I discovered it today and investigated.
As I only allow one profile, I had to do a dirty fix. Create a URL menu item and link directly to the page flash uploader page.
