Error 500 on login for all users but superadmin

Hi,
I'm using joomla 1.7 as a new site (no upgrade...). The module is installed correctly (or at least it seems so). Users can register, receive a password by email and connect.
I don't understand why, each time a user try to connect with the new password received, I've got an error 500 page. If I grant the super user group (and only this level) to this user, only then can he login...
Any clue or idea?

I've got to precise:
- that the page to be accessed after login is public (homepage).
- I haven't dis-activated the joomla plugin authentification, because if so, I can't connect to the administration interface of joomla anymore!!!
Best regards

Where did you see that you have to deactivate the Joomla plugin authentication?

Please take some time a read the installation document.

Thx you for you reply Nick,
I've read thoroughly the documentation, and because I checked everywhere (interface/documentation) where a level access could interfere and found nothing... finally I opened this topic.
I just opened my new site and this login part is the last but not the least difficulty I need to resolve. I would be disappointed to quite CB, because it does exactly what I need. But it would not be good to have only superusers...

NB: I think I start to have a good command on joomla for the little time I've been working on it already, but sometimes documentation could be confusing or ambiguous on terms being used: The disactivation I tried (because I tried anything, guessing I might not have understood something correctly) is coming from the paragraph 2.10 p 21 : "deactivating the Joomla/Mambo Login module and the Mambo Logout module..."

and happy new year...

Well this is not a CB issue as CB is working just fine everywhere else I have tested,

Did you follow instructions from the installation document included in the CB 1.7.1 package?

Did you create a public menu item to CB Profile as the installation guide instructed?

The documentation you quoted clearly says Login module - it says nothing about plugin!

I suggest you turn on Joomla debugging and check you webserver error log for additional messages.

and happy new year...

Happy New Year!

Ok Thxs a lot for your suggestion. It was a good one: Thus I found that I forgot that I changed the rights for the public on the configuration.
All is working perfectly!
