Webpage Composer end user permission problem

Hi Gurus,

Please help me to solve this pblm.

After creating a site & its role using WPC, i have assigned its role to 5 different users.

But this site page is not visible for some users, while some r working fine.

I noticed that this pblm is with only end users.

Its workin fine with those users who r having SuperAdministrator role.

But i want to publish it to End users also with out assigning SuperAdministrator role. What should i do to present it to endusers.

Thanks in advance

Vipin
