Hi,
I’ve upgraded a few old sites to Umbraco 10.5.1 and have had a strange error:
Cannot bind source content type Umbraco.Cms.Web.Common.PublishedModels.Home to model type Umbraco.Cms.Web.Common.PublishedModels.Home. Both view and content models are in memory generated, with different versions. The application is in an unstable state and should be restarted.
I’ve seen this error three times across three different sites over the past week or so. All are on 10.5.1 and I don’t believe I’ve ever seen that error under Umbraco 7 or 8. Going into IIS and restarting the affected site fixes it, but there must be a reason that it occurs in the first place. It seems to always be the home page that falls over; other pages still work.
I realise that this is a bit vague, but can anyone give any advice around how to troubleshoot this and track down what’s going on?
