You might want to check the log files in the tomcat installation directory for startup errors.
(Unfortunately tomcat writes logs in several files, at least last time I checked. Just look into everything that has updated recently in the logs dir) A possible cause for the problem is that you have two xwiki webapps running in the same tomcat; maybe caused by having a custom context.xml duplicated or the like (?) But without the startup error from the log this is just a wild guess HTH Clemens ----- Ursprüngliche Nachricht ----- Von: Gervwyk Am: Mittwoch, 18.11.2015, 14:57 An: Xwiki Users Betreff: [xwiki-users] XWiki startup HTTP 500 issue > Good day. > > Had xwiki set up and running for a while now.
