So sorry for the situation. It appears that the issue appears because of the WpStream experimental theme and the latest plugin update of WpStream. Unfortunately, since it is an experimental theme, limited support is available and we are not sure when such an issue can be addressed. Our sincerest recommendation is to change your theme to any other one on WordPress as our WpStream plugin is compatible with any theme out there.
We apologize for the disruption this is causing but I hope that you can understand.
