Error in Macro Behaviour after Upgrade to Confluence 6.13.9

[Florian Seifer]

After Upgrading to a new Confluence Version we noticed several strange changes when Macros where involved:

- When Editing a Page, its Macros have no Description or Parameters shown, except when "Properties" is selected.

- Some Macroboxes are not shown at all in Edit-Mode but are displayed in the normal view-mode, thus the original Macros can not be changed anymore.

- The {Status} Makro for example has no Text rendered to it in Edit-Mode but again is displayed normally in "View"-Mode (See Screenshots at the End)

Due to the variety of symptoms, and the multitude of possible causes, we are currently at a loss how we should even narrow down a possible explanation.

Every Idea that any of you could offer would be greatly appreciated.

With kind regards!

Hello @Minh Tran 

Thanks for your quick response.
Concerning the Macros I have not noticed any specific exceptions in the logs. But while researching I stumbled upon a possible issue caused by missing fonts required for newer confluence versions. This has been reported to cause Problems with Macro rendering as well as prohibiting the correct depiction of a Captcha while logging in.

For the CAPTCHA Error I noticed the following exception in the logs:

2020-01-09 09:41:09,966 ERROR [https-jsse-nio2-8443-exec-18] [ContainerBase.[Standalone].[localhost].[/]] log Unhandled exception occurred whilst decorating page

Which Google also points to the fonts issue as described here:

Sadly the prescribed fix did not work in my case or I did something wrong.

@Florian Seifer I very much suspect you are hitting the font missing in your Linux server?

Can i ask you to install the fontconfig for that?

What Linux distro are you using for your Confluence server?

[Florian Seifer]

@Minh Tran 

We are using RHEL 7.7.   

And as I already installed the following fonts:

yum install ghostscript
yum install dejavu-fonts-common
yum install dejavu-sans-fonts
yum install dejavu-sans-mono-fonts
yum install motif

cleared the plugin caches and restartet confluence.

Did I miss something?

One thing I find odd is that I NEVER observed the "garbled" symbols you can see in the image of the KB article: 

[Minh Tran]

Can you try with

yum install -y fontconfig

[Florian Seifer]

yum install -y fontconfig

[Minh Tran]

Interesting. What previous Confluence version have you used before upgrading to 6.13.9?

[Florian Seifer]

6.9.3

From your information I don't think this is related font issue. I believe you are hitting a bug in Confluence. Is your license able to create ticket at https://getsupport.atlassian.com then our support engineers will assist you?
