Hi,

The replies that mentioned clearing the meta preference field made me realize where the problem is.

  • The Live Data widget is using the org.xwiki.platform.html.head UI Extension Point (UIXP) to inject stuff in the HEAD of the HTML page.
  • this UIXP was introduced in 11.1RC1 as org.xwiki.platform.head and then renamed in 11.5 as org.xwiki.platform.html.head
  • before Loading... (17.4.0RC1) it was provided by the meta preference field, but now it is provided (by default) by the meta.vm Velocity template

The problem is that the meta preference field is often customized. This means that:

  • someone upgrading to 11.1+ might have chosen to keep their custom value for the meta field, missing the UIXP
  • someone upgrading to 11.5+ that had the previous UIXP name might continue to use the old name, if they chose to keep their custom value of the meta field.

This UIXP wasn’t used much before Loading..., but now Live Data depends on it. So if you have previously customized the meta preference field you need to review it and make sure it calls the org.xwiki.platform.html.head UIXP. Compare your custom value with the content from the meta.vm Velocity template.

Hope this helps,
Marius
