Hi people, I have a newsletter content type that has an EVA field, I use html mail for send the emails, yesterday my emails worked ok, all the html and my eva field in the newsletter emails worked ok. But now i do not understand why, my newsletter emails does not arrive with the EVA field, i tried EVERYTHING create a new eva field, quit all the html, send in plain text, but anything works. But if you go to the newsletter node you will see the Eva field normally (see attachments).
