After installing the product and set permission settings, the permission doesn’t working at all. Anyone sees all views or columns.
The most possible cause is that the product has not been deployed correctly to the web application that the current site collection belongs to. Please go to Central Administration, and find Manage farm solutions, locate the solution and deploy.
Additionally, the permission won’t take effect on site collection administrators. (Refers to online tutorial)
