 * Do you guys have Jetpack installed?, cause I just installed Jetpack and now I
   have the same issue with request error not json. I thought it might be the JSON
   API module in Jetpack so I disabled it but still have the issue, had to deactivate
   Jetpack to have Mailpoet work correctly. 🙁

 * Hello
 * I have the same problem and Jetpack isn’t installed.
    But when I modify the theme
   of the newsletter and send a preview it’s work, then when I return to the first
   theme, it’s work also.
 * I do not understand what is happening.
 * Thanks for help.
