I've created a new service desk and when customers attach files, the files only appear as text e.g. a Picture will attach as !picture.png|thumbnail!
We've tried multiple file types and the same occurs when adding attachments in comments.
We have another service desk that doesn't have this issue. The same attachment field is used in that service desk. The customers and the service desk agents have permissions.
We can't figure out what the issue is, are there any suggestions?
