Hi, I have just installed xwiki 9.3 and I am having problems with the notification settings. I've used tomcat9, mysql14 on centos 6.9. On the user profile, Notifications Preferences option I cant change the notification settings. Every time i toggle the option I get an error: "Failed to save your settings" and get this error on the server: mai 09, 2017 11:19:02 AM org.restlet.engine.application.StatusFilter doHandle WARNING: Exception or error caught in status service java.lang.IllegalStateException: The Web form cannot be parsed as no fresh content is available.

Do you think it could be related to this issue? Is there any logs I could check for adicional errors? thanks -- View this message in context: http://xwiki.475771.n2.nabble. com/Error-saving-Notifications-Preferences-tp7603801p7603903.html Sent from the XWiki- Users mailing list archive at Nabble.com.
