After upgrading to v.3.6.2 there is no html input-field at the first page of a new campaign. I can see the headline (Nachricht erstellen) but no field to fill in.
For me that would not be a problem, because I only send text-mails. But if the html-field is empty (or missing), I get an error-message, when starting the campaign and nothing works.
I tried to reinstall the files manually, but have the same problem afterwards.
Is there anybody, who knows what’s wrong?
