Hallo,
After upgrading confluence from 6.7 to 6.8 i always get the screen with:
Confluence had problems starting up.
According the logs there are no more errors:
2018-03-28 12:25:32,649 INFO [localhost-startStop-1] [com.atlassian.confluence.lifecycle] init Confluence is ready to serve
First upgrade i got errors on the database connections and the proxy .
I corrected these errors and I can not see any errors in the log anymore.
However i still get the screen "Confluence had problems starting up"
