We are using dupermagpro. Customizing the theme always produces an error-message on saving (the changes made ARE SAVED thoug). The message displayed in german: “Etwas scheint schiefgelaufen zu sein. Warte einige Sekunden und versuche es dann erneut.” (Somthing seems to have gone wrong. Wait for a few seconds an try again.) Trying again shows the message, that all the changes have already been applied. This acutally happens with supernewspro as well. It did not haben with dupermag (the free version). Any idea?
