Since some time after version 11.10.6 the following features stopped working:
How to reproduce for local blocks:
At this stage, the 11.10.6 version shows all available block types while the latest version shows an empty list.
How to reproduce for ContentAreas:
In both cases above, the CMS attempts to get all available content types using the following endpoint: /EPiServer/cms/Stores/contenttype/?query=getavailablecontenttypes
The 11.10.6 version includes the parameter &localAsset=true while the latest version does not. Calling the endpoint directly with the missing parameter returns the correct result in the latest version.
Is this a known bug? Is there a fix scheduled? Does anyone know of a workaround?
Sounds a lot like this bug?EPiServer.CMS.UI.* 11.19.1 packages break content area 'create new block' link functionality
If that is the bug described, the fix is contained in version 11.19.2 and higher.
