If you can view your course content but can't comment because the comment sections are locked and preventing you from posting comments or replying in the discussion forums, you need to activate your community access. The Inner Circle community is a private area, and members have to be invited to this space. 

To get your access and become able to participate in conversation forums,  please follow these steps:

1) Navigate to the Inner Circle access page at the Inner Circle Link

2) Log in with your credentials.

3) Once logged in, click on the specific course link to activate your Inner Circle access for that course (refer to the image below for guidance).

4) Verify if the forum for your course is active. An active forum will display a colored bullet next to it in the community menu (see screenshot below for an example).

5) Repeat the process for all your courses.
