confluence 500 error while creating a child page

[Sys Admins]

Hi,

I have the following error:

Confluence is erroring out with the following Java exception:
com.atlassian.cache.CacheException: java.lang.NullPointerException at
com.atlassian.cache.ehcache.DelegatingCache.get(DelegatingCache.java:101)
caused by: java.lang.NullPointerException at Unknown location

I have tried do this (How to clear Confluence plugins cache):

https://confluence.atlassian.com/confkb/how-to-clear-confluence-plugins-cache-297664846.html

Did not help, any ideas?

Regards,

Tony.

Seems like one of the plugins can cause this. Try to search through this https://jira.atlassian.com/browse/CONF-39555
