Error rendering WebPanel

Sushma_gan0w9

Hi Team

I am getting the below error when I restarted the confluence Server.

Error rendering WebPanel (com.atlassian.confluence.plugins.confluence-dashboard:dashboard-server-side-soy/DashboardTemplates.App.serverSideLayout): Could not find custom mapper jackson2soy for class class com.atlassian.confluence.api.model.web.WebItemView

How to resolve this ?

Hello,

It looks like something is wrong with web panel plugin. Did you apply the resolution stated here:

https://confluence.atlassian.com/confkb/error-rendering-webpanel-no-renderer-found-for-resource-type-300814261.html

Hi @Elifcan Cakmak

I tried with both the resolutions. Both didn't worked for me

1.With the First resolution

I followed the first procedure i.e I added the -Datlassian.plugins.enable.wait=300

argument to Java properties in the setenv.sh file. Then I restarted the server.But No luck

2.With the Second resolution

[root@inblrvyd lib]# java -cp h2-1.3.176.jar org.h2.tools.Shell

As you can see , BANDANAVALUE not containing the below lines which are expected to be deleted.

<entry>
  <string>confluence.web.panel.renderers</string>
  <boolean>false</boolean>
</entry>

I am really confused .Both the solutions are not working

please help me out.

Thanks in advance

Hello,

These are all info logs. Are there any error logs in the log file? Also you can try to stop confluence, delete plugin cache directories and restart confluence again. These are the directories:

<confluence-home>/bundled-plugins
<confluence-home>/plugins-cache
<confluence-home>/plugins-osgi-cache
<confluence-home>/plugins-temp
<confluence-home>/bundled-plugins_language

I suggest taking backups of these directories before deleting them.

Regards,

Elifcan
