setting user group functions

[llegrand]

In working in the EDIT USER GROUP section -  I am having difficulty in some of the links, and some quite unsatisfactory results in trying to find what the links go to.

I am of course logged in as the administrator.  As seen here:

/index.php?rt=user/user_permission/update&user_group_id=10&s=......



All of the entries show  GO TO PAGE  when hovering.  However the results are varied:

Some links actually work and go to the page it controls.

some places I get this - with no ability to log in.  Note: this seems to happen a lot with anything that has 'extension' in the title.
{"error_title":"Login Error!","error_text":"You are not logged in. You will be redirected to log in
page","show_dialog":true,"reload_page":true,"error_code":401}

things with grid' in the title display like this when they work:

index.php?rt=listing_grid/zone&s=.......
{"page":null,"total":0,"records":"65","rows":[{"id":"3647","cell":["United States","\n\t\n\t
\n \n <\/div><\/div><\/div><\/div><\/div>\n<\/span>\n","\n\t\n\t
\n \n <\/div><\/div><\/div><\/div><\/div>\n<\/span>\n","\n
\n \n <\/span><\/div><\/div>\n<\/span>\n"]},{"id":"3615","cell":["United States","\n\t\n\t
\n \n <\/div><\/div><\/div><\/div><\/div>\n<\/span>\n","\n\t\n\t


Some just go to blank pages

I don't know if these differing results on GO TO PAGE click are by intention or there is an issue. 

But a more reliable way to determine what the link is linking to would be appreciated.
