Visual Composer - Permission denied

hello friends,

My visual composer is giving authentication exception ..

<b>I am tryng to log in using J2EE_ADMIN , it says "Roles specification: You don't have a Visual Composer role.

"</b>

i have installed the required SP7 patches , .

please let me know what exact role do i have to assign to J2EE_ADMIN , and under what parent role does this role comes... i guess the child role name is VCRole.

please correct me if i am wrong.

thanks

rohit
