Hello @tardar

could you perhaps tell a bit more about your environment? What are you running the xwiki on , from what version did you update?

I suspect you’re using tomcat and depending on where you updated from it might be the java version but that depends on the situation!

Hello @tardar,

This is probably Loading....

You can fix this by removing the most recent folder of data/extension/repository/org%2Exwiki%2Econtrib%2Econfluence%3Aconfluence-xml (or the whole confluence-xml folder altogether). Your wiki will restart fine, and you will need to install confluence-xml again.

Sorry for this issue.

Make sure to install confluence-xml version 9.53.2 or later. 9.51.1 is the bad version.
