CQ 5.2 taglibs not working

[Community_Admin]

Our development author node went down today with the following error on every page:

org.apache.sling.api.scripting.ScriptEvaluationException: org.apache.sling.scripting.jsp.jasper.JasperException: /apps/myApp/components/page/base/base.jsp(1,1) The absolute uri: http://www.day.com/taglibs/cq/1.0 cannot be resolved in either web.xml or the jar files deployed with this application

It's failing at the setup of the tag libraries in /libs/wcm/global.jsp

There's nothing we did out of the ordinary, just some standard component edits and then this error. I've searched around for a few hours but can't find anything to solve the issue.

Any ideas would be gratefully received

Sometimes we encounter this error even if there are some errors in your bundles. Check if you all your bundles and components are active.
