When accessing any page that contains the outgoing-links macro, the page will display the following error:
All supported Confluence and Linking add-on versions
CauseThere is a user macro named outgoing-links and it is conflicting with the outgoing-links from the Linking app.
By default, users cannot create a user macro with the same name of an existing macro. However, older versions of Confluence do allow you to create a user macro and then install an add-on that contains the same name of the created user macro.
For example, a user macro named outgoing-links was created. Then, the Linking app was installed, which also has a macro named outgoing-links. Thus now there are two macros with the same name.
This is fixed by renaming the user macro with a unique name.
