I have tried.
I clicked the cog icon >> Add On >> Manage Add ons >> Filter with renderer in System drop down>> Expand "Wiki Renderer Macros Plugin" here I observe that 7 out of 8 modules are active and last one which is inactive is "Use HTML code within a JIRA Issue. Do not enable unless you understand the XSS security implications." also it says Module cannot be modified.
Am I doing it the right way, if not please help me enable, rich text enable in comments. I have already enabled it for Description field.
