HTTP Status 500 – Internal Server Error

colethegamer · December 12, 2019, 7:05am

Hello everybody,

I need really urgent help about this problem. Our manager needed an Xwiki site what I created on a freshly installed Ubuntu server. The xWiki was running perfectly until I rebooted the machine ( Virtual ).

Since then it goes to initalize until 50% and stucks and drops error messages:

Message com.xpn.xwiki.XWikiException: Error number 11007 in 0: Failed to extract Entity Resource Reference from URL [http://10.235.2.91:8080/xwiki/bin/view/Main/]

Description The server encountered an unexpected condition that prevented it from fulfilling the request.

Exception

You made some changes to the hibernate file and you’ve used some wrong info in there. Or your DB has changed (new password, new user, etc) and the info in this file don’t match anymore.

So you need to review your hibernate.cfg.xml file content.
