Hi, I've a big problem...
After login users can't see nay course, but every course ha free subscription and is set to visible in home page....
They can see courses only if I subscribe them to the course, manually...

Any help, I'm going crazy... 

Noone knows how to make visible every course? I'm shocked...

It is most likely there.  Try logging out, then claring your cache, then logging back in.  Sometimes it takes restarting your browser as well.  Not sure why it does this, but it does.

Hope this helped. 

Thanks Terry!
unfortunatly nothing changed...
I tryed restarting/changing browse, pc, mac, user, clearing cache, using a brand new browser but always nothing...

Now I'm trying with a frsh install of 4.0.5...I'll inform you if it  will work...

Nothing changed... I've no other ideas...

There is a way to autosubscribe user after registration? 

There is a setting in the course details that will allow auto-unsubscribe.  You can also remove yourself from the course using the subscription feature.  I hope you find an answer to your original question.
