Summary
While in page edit mode, editing links, or trying to insert different macros, such as Jira Issue, Status and inserting an image to the page etc, does not render anymore.
Environment
7.13.2, 8.5.4
Diagnosis
Use the "fc-list" command to check different fonts installed on the system. This command will only work if fontconfig is installed, 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.
atlassian-confluence.log may produce errors similar to those seen below when attempting to edit pages.

Cause
The cause is 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.
