Flexiaccess - Module mainmenu not displaying

Hi,

I am using Flexicontent 1.3 & Flexiaccess 1.0.5.

I set up a menu and its module (mainmenu) which should be restricted to some members.

In Flexiaccess, I set up a new group and added all the members to it.

In "Frontend & content" I set the appropriate permissions on the module for this very group and above. And I also set the READ permissions to children.

When I log in in front end, no menu.
The only way to have it showing is either to set the permissions to "Public", or to set the Joomla "registered" access stuff and to log in; which means no flexiaccess management.

The funny thing is that it all worked for a while, but since the latest update, I came across some bugs and hicups. And this one, I just can't work it out.

Any idea?

Thanks
Antoine
