Table of Contents Macro does not display on KB Pages from within the Customer Portal

Summary

When a Confluence KB Space is linked to a Service Desk project, the Table of Contents Macro is not displayed on any page containing the macro when viewing from the Customer Portal as a Customer.

Steps to Reproduce

1. Link a Confluence KB Space to a Service Desk Project
2. Add a Table of Contents Macro to any page of the Space
3. Visit the Customer Portal directly from the Portal URL
4. Search for the page that contains the Table of Contents Macro
5. Select the Page to view it

Expected Results

The page loads in a modal window and should contain all content added to the page, including the Table of Contents Macro.

Actual Results

The Table of Contents Macro is omitted from the page, and all other page content works as intended.

Workaround

The workaround we found is to use the Table of Contents Zone macro in the New Confluence Editor instead. Brief steps are as follows:

1. Add Table of Contents Zone to the page.
2. Edit the macro and include the main body/text of the page is inside of the macro.

3. Save the macro and publish the page.

4. Go to the portal and search for this page.
5. The complete page shows up including the macro output.
