Get a yellow screen when accessing Experience Editor after Sitecore 9.3 upgrade.
Message is - sitecore Method not found: 'Void Sitecore.Pipelines.GetChromeData.GetChromeDataProcessor
Glass Mapper SC is used in the project.
Is there a workaround?
In Sitecore 9.3 there is a lot of old Obsolete code removed, one of the things that is removed from the Sitecore.Kernel in the Sitecore.Pipelines.GetChromeData.GetChromeDataProcessor is the [Obsolete("Please use another constructor instead")] public GetChromeDataProcessor() So you need to use another constructor.. public GetChromeDataProcessor(BaseClient client) Search in your code where you use this? or take a look at the full stacktrace is there any custom code named? Or possible there are some old files from Sitecore left in your webroot that causes the issue.
