1. Clear the Plugin Cache - Delete the following directories:
   • <confluence-home>/plugins-cache/
   • <confluence-home>/plugins-osgi-cache/
   • <confluence-home>/bundled-plugins/
   • <confluence-home>/plugins-temp/
   • <confluence-install>/work
2. Start Confluence.

We have seen reports that clearing the browser cache may be required in some cases, and we would recommend taking this step where possible.
