If you are sending a message from your Messages via the Wyzant website, there is an optional setting at the bottom of the text box that reads “Press Enter to Send." If pressing Enter sends your messages, it is likely that this setting is enabled. Simply un-check the box box to disable. Please note that this box should be unchecked by default. If you are continuing to encounter this issue after disabling the setting, clear the cookies on your web browser and then revisit the messaging screen.
