Old Version: 6.13.6
New Version: 7.4.6
We upgraded confluence in our dev stage. Before the upgrade we switched to 'Safe Mode' and after upgrade unable to 'Exit safe mode and restore previous configuration'.
We are facing below error.
'System failed to restore from Safe Mode. Reenabling plugin Composition failed while exiting safe mode'
In the logs we can see below error messages.
availableForTraversal Cannot determine required plugins, cannot resolve bundle 'net.customware.confluence.plugin.composition'
We tried after clear the confluence cache as described in https://confluence.atlassian.com/confkb/how-to-clear-confluence-plugins-cache-297664846.html.
But we faced same error.
In the logs we can see connection failed to atlassian market place as well.

We tried after disabling UPM connection to the market place as described in below. But still we are facing same error. https://confluence.atlassian.com/upm/configuring-marketplace-connectivity-306350947.html
