Harry Metske commented on JSPWIKI-820:
--------------------------------------
Do you have the contents of jspwiki.log ? That should provide more info on the
cause of the error.
If there is no jspwiki.log, then please check the log4j configuration. You can
place a log4j.properties in your tomcat's lib directory.
See
https://jspwiki-wiki.apache.org/Wiki.jsp?page=Documentation#section-Documentation-ConfigurationAndAdministration
and
https://jspwiki-wiki.apache.org/Wiki.jsp?page=Configuration#section-Configuration-LogConfiguration.
Especially the jspwiki.use.external.logconfig property.
regards,
Harry
