Hi, all.
I've just created a new Openfire 4.0.1 instance (on CentOS 7, OpenJDK 1.7.0_111, integrated with Active Directory), which will take the place of an ancient 3.6.4 instance. While I have no problem editing my profile in Spark 2.7.7 when connected to the old Openfire instance,I get this error when connected to the new instance:
Server does not support VCards, unable to save your VCard
I get this despite having "Avatar/VCard - (Spark Only)" enabled in Openfire.
Your help would be greatly appreciated.
