Vavilon I didnt  explain very well.
It is like this when you copy permissions to a new membership level for example from standart to newmemberlevel , some pages of some modules will not be seen to this newmemberlevel as default.
For this you need to go to pages and check especially system pages there. 

You will see there while some pages are selected to be seen to the standard level that you copied, they will not be selected for the newmemberlevel. 

You have to click also for the new member level for these pages to be seen by that membership level.

Otherwise these pages of the modules will not be visible for the newmemberlevel.
