I have the same problem

Mailpoet 2.6.6
Wordpress 3.9.1

Is there any solution for this problem?

thx

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.
