Thread:Extension talk:Wikibase Repository/Wikibase extension error - failed to deserialize on EntityFactor.php/reply (4)

what do you mean about the namespace? I am trying to fix some issues we have in the UI data since august dump that we are not able to render correctly with unrecognize modules or templates getting displayed in the UI: "mw:Help:Magic words#Other" and I thought could be this extension that we have missed, any help would be useful
