Error HTTP Status 500 after Confluence installation

[Navadeep]

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.

1. Verify that Confluence has stopped
2. Delete the felix folder in C:\Program Files\Atlassian\Application Data\Confluence\plugins-osgi-cache\
3. Try starting Confluence

Thanks,

Navadeep

What does the application log say is going wrong?  Should be in <confluence-home>/logs .  Might be worth a look at the server log too - catalina.out in <confluence-install>/log
