Hi, I'm trying to use the Configuration->Organization->OxTrust Settings UI to change the Organization Logo and Favicon. When I upload an image, it appears to upload but then I get an "Oops. Something wrong happened." error. /opt/gluu/jetty/identity/logs/oxtrust.log has the following error (full stack trace below): 2018-06-07 06:16:20,313 ERROR [qtp1744347043-14] [org.gluu.oxtrust.exception.GlobalExceptionHandler] (GlobalExceptionHandler.java:61) - Unrecognized Content Type. java.lang.IllegalArgumentException: Unrecognized Content Type. This prompted a couple of questions: 1) Do you have any guidelines for this logo (png / size etc) 2) Any thoughts on why this is occurring? I downloaded a copy of the logo.png from the gluu login page and tried to upload it and it also had the same issue. In the meantime I will have a go at the process described here but thought it worth raising / asking? https://gluu.org/docs/ce/operation/custom-design/ Full stack trace: 2018-06-07 06:16:20,313 ERROR
