Previously, the knowledge base articles in our portal could be accessed with or without the language code in the URL. For example, https://softwaresupport.3dsystems.com/knowledgebase/article/KA-03409/en-us and https://softwaresupport.3dsystems.com/knowledgebase/article/KA-03409 would direct you to the article on the portal. Now, the article is only accessible if the language code is added to the URL. Is this by design because of creating different language versions of the articles? Has there been some sort of update that causes this? Has this always been the case and just never noticed it? We've recently published a number articles in different languages, could this be cause and how it will be going forward?
The Redirect option in the portal doesn't seem to be a quick fix for this as it isn't redirecting.
