Advanced Editor empty after upload?

A new problem started last week.


I upload a new email, and it appears to go OK, but when a user tries to pull it up in the Advanced Editor, the Advanced Editor page is empty, incomplete (image attached).Screen Shot 2016-09-06 at 12.08.29 PM.png


What am I suddenly doing wrong?


Thanks for any help.





Thank you for reaching out to the API Support team here at Constant Contact.


It appears you are running into a known issue with creating emails with unsupported characters within them. In looking at the HTML that came over for this email, I found an instancea of a "smart" or "curly" apostrophe. Though it appears similar ( ’ vs ' ), only the standard apostrophe (the second one) is available to be used.


While this should return an error, the known issue is that we are creating the email with these special characters anyway. This issue has been brought to the attention of our engineering and development teams for investigation. The workaround at this point is remove any of these unsupported characters from the code before submitting.


You should also be able to PUT to any campaign having the issue to update the code with a corrected version that does not contain any unsupported characters. For details on how to PUT to update your email campaign, see


Please let me know if you have any other questions.
