Hi Beitmann,

From the look of your error message you should try purging your Confluence plugin caches and see whether that resolves your issue. You can do this by following the steps outlined below:

1. Shutdown Confluence
2. Delete the following directories
<confluence-home>/bundled-plugins folder
<confluence-home>/plugin-cache folder
<confluence-home>/plugins-osgi-cache folder
<confluence-home>/plugins-temp folder
3. Restart Confluence

All the best,
John
