Hi ,
I have upgraded the Confluence Installation from 5.6.4 to 5.7.6.
I was not able to launch the Confluence after the upgrade. Here is the error screenshot. I have tried below solution. But this didnt workout.
- Verify that Confluence has stopped
- Delete the felix folder in C:\Program Files\Atlassian\Application Data\Confluence\plugins-osgi-cache\
- Try starting Confluence

Thanks,
Navadeep
