Confluence plugins not working

Question

After upgrading the confluence and moving to a new server the some plugins don't work and plugin browser doesn't load either.

To do the we followed the steps:

* rsync confluence and confluence-data

* download the confluence-4.3.3 installer

* point installer to the confluence folder to do the update

Also, some messages on the interface doesn't show instead the message key shows e.g. easyuser.add.users.button

Hi Ali,

Judging by the errors, I believe this was due to a failed upgrade process. So rather than start troubleshooting each problem individually, I suggest that you roll back to a pre-upgrade state and attempt the upgrade again.

I recommend using the standalone bin file, instead of the installer that is known to cause trouble. Please refer to https://confluence.atlassian.com/display/DOC/Upgrading+Confluence+Manually for that.

Cheers.
