Summary

While in page edit mode, trying to insert different macro's such as Jira Issue, Status, etc does to render anymore. 

Environment

7.13.2

Diagnosis

Use "fc-list"  command to check different fonts installed on the system. This command will only work if fontconfig is installed and so, if this does not work, then kindly refer to Confluence Server 6.13 or later fails with FontConfiguration error when installing on Linux operating systems to install fontconfig or equivalent (based on your Linux distribution) before proceeding further on this. 
Post running this command, if the results are empty, then follow the below steps. 

Cause

This is happening as we are missing system fonts installed under /usr/share/fonts  directory and usually would be observed when we are installing Confluence on a new system. 

Solution

Copy the files under this directory from another working system of the same variant or directly download the system fonts for the specific Linux variant. 

Once done, use "fc-cache -v"  to rebuild the fontconfig cache and check again.
