chart plugin update to 2.0.4 fails

I am trying to update the Chart Plugin from 2.0.2 via the add on manager. The update fails with "An unexpected error occurred. Refer to the logs for more information."

The logs in /opt/atlassian/confluence/logs/ contain no further information.

Can you find atlassian-confluence.log in the Confluence home directory? Confluence Home directory is defined in <Confluence install folder>/confluence/WEB-INF/classes/ file.

Did you encounter the same issue trying to install/update other plugins via the manager? How about manually download the plugin jar from and manually upload it from the manager via "Upload add-on", will it works?

Also, ensure that the url you use to access Confluence via the browser matches the url configured in Confluence Admin > General Configuration > Base URL. This url mismatched could cause a failed plugin installation/update too.
