[LadeliaB]

Since Friday, I have been getitng issues with previewing and testing email messages.  It pops up with "Oops, Something went wrong".  How do I fix this?  Really need to get this message out today.  I have tried other browsers and logging out/in.

Are you having this problem with the Preview/Test API or with our WYSIWYG editor in our product using the Preview/Test feature there?
