Im facing a problem in the Jive Cloud version... When I'm uploading a 600kb JPG file occurs an error that indicates that my file is too large. This is new because before I have uploaded large images like 10mb without problem.
I have searched this error in the Known Issues November 4, 2016 but not found
Reviewing through your description I would recommend submitting a case in your customer group here in the Jive Community as a next step so that a member of our support team can perform further investigations specific to your instance. When submitting the case if you could provide a copy of the file you are seeing the behavior with it should assist them in their testing.
