org.apache.catalina.core.StandardContext.startInternal One or more Filters failed to start. Full details will be found in the appropriate container log file
Asked by Estelle_Hewett:

Restoring Confluence from backup. and running it (it worked with previous versions) this time (excluding attachments this time) it bombs out with the following error.

**SEVERE \[localhost-startStop-1\] org.apache.catalina.core.StandardContext.startInternal One or more Filters failed to start. Full details will be found in the appropriate container log file**

Is there any further logging i can enable for logging for this particular type of fail, to indicate which container/filter caused an issue?
