As you are aware, to clear the cache in ‘Dynamics Portals’, you need to login with a Portal user with ‘Administrators’ web role and

• Navigate to {Portal_url}/_services/about.
• Click on ‘Clear Cache’ button

But what if you don’t see the ‘Clear Cache’ button, even if you logged in with ‘Administrators’ web role?

We encountered the same and were getting a blank screen when we browsed ‘_Services/about’ by logging in with ‘Administrators’ web role.

Reason:

• Even though you are having ‘Administrators’ web role, you may be missing ‘Website Access Permissions’

Fix:

Grant the missing ‘Website Access Permissions’ to ‘Administrators’ web role by following below steps.

• Open your Dynamics application
• Go to ‘Advanced Find -> Web Roles’

• Open the ‘Administrators’ web role
  • Note : If more than 1 Portal solution (i.e., Custom Portal, Self service portal etc..) enabled, you will see more ‘Administrators’ records. Make sure you filter with ‘Website’.
• From the navigation, open the ‘Website Access Permissions’

• If no existing records in ‘Website Access Associated View’, create a new record (Note: If there is existing record, open the same)

• In the new record window, select all the checkboxes under ‘Permissions’ section.

• Save and Close.
• Now from the Portal, browse {Portal_url}/_services/about
• You should get the Portal Details screen with ‘Clear Cache’ button.
