Hi Customer reported the issue with freemarker theme.

They have a freemarker theme deployed Freemarker theme in their environment on a page. A test user with only User role with all permission under My Account revoked, when the test user try to visit the page with freemark theme page, the system return error and also the page will not render.

Reproduce Steps:

1. Log in as Administrator.
2. Revoke all the Permission Definition for User role in "My Account" section.
3. Create a new user named "testuserqantas" (do not need manually assign User role to the user since it is done by default)
4. Create a test page
5. Deploy Freemarker theme for test page(Sunset Theme from Marketplace in this case)
6. Log out Administrator account, and Log in with "testuserqantas" account.
7. Click on the test page.

Observed Behavior: When accessing the Freemarker theme page, the page will not render and console return with exception
