Reftagger theme component

[RGJ (Richard - Communiteq)]

First is the message that component needs updating.
[Admin Notice] Theme ‘Reftagger’ contains code which needs updating. (id:discourse.script-tag-discourse-plugin) (learn more)

This has been resolved now.

@BrianC

Second may be related to the first notice where the component needs updating. References are not being tagged and pages seem to hand showing the loading circle in the browser tab.

This I cannot reproduce, even before resolving the above issue - which was merely a warning, not an error.
