Re: [xwiki-users] Wiki 4.5.2 broken

Hi Jeremie, I hit the same problem a few days ago when I upgraded xwiki.org . Thomas has fixed it for 4.5.3 ( https://github.com/xwiki/xwiki-platform/commit/53399e652e527794384a4a588d59… ) which will be released ASAP. The problem is in /repository/external/.xwiki/ data/jobs/status/extension/action/org.xwiki.enterprise%3Axwiki-enterprise-ui/wiki%3Axwiki/status.xml . You can "fix" the problem quickly by deleting it.

(or better move it to some backup folder) but unfortunately the side effect is that xwiki-enterprise-ui will not appear as installed any more so you'll have to "reinstall" it (which means solving a lot of merge conflicts).

Best is to wait for 4.5.3.
