Steps to reproduce:

1. Create a new blank site called Site 1 and add a page to it called Page 1.
2. Add the calendar portlet to Page 1 and enable calendar event comments on the Site 1 calendar.
3. Add an event to the Site 1 calendar.
4. Create a new user and assign this user to Site 1.
5. Sign in as the new user and try to add a comment to the event in the Site 1 calendar.

Expected result: Comment is added successfully.
Actual result: "Error: You do not have the required permissions" pops up.

Further testing:

1. Added a new site role called Site Calendar Event Commenter and defined the Calendar -> Calendar Event -> Add Discussion permission for this role and assigned this role to the new user for Site 1.
2. Signed in as the new user and tried to add a comment to the event in Site 1.

Expected result: Comment is added successfully.
Actual result: "Error: You do not have the required permissions" pops up.
