Hibernate Exception with XWIki 9.4

Hi,

we are using XWiki 9.4 and getting the attached exception.error

However, XWiki seems to work fine, but I think its not an intendent exception :wink:

How can I fix it?

According to the error you installed Repository application but then you messed with ExtensionCode.ExtensionProxyClass document.

You should probably go to http://yourdomain/xwiki/bin/admin/XWiki/XWikiPreferences?section=XWiki.Extensions&search=repository&repo=installed, ask for a diff of the extension (“compute changes”) and revert everything that was not supposed to be modified. See http://extensions.xwiki.org/xwiki/bin/view/Extension/Extension+Manager+Application#HComputeChanges for more details.

Thanks! This problem has now been perfectly solved!
