API Illegal string offset 'content'

[jra2f]

Hello,

I'm using the API for a couple of years to generate campaigns.
The code is in a php file called by a bigger script that deals with a couple of steps before to generate the content.
Recently I modified the code to generate 2 identical campaigns for 2 lists, with the lists IDs in an array.
(I only took the working code and wrapped it in code to use the array)
It was working the last time I used it a couple of months ago, (I also tested it a lot) but today there's an error showing up and I don't know what is the problem as it is in a part of the code I didn't change.

Warning: Illegal string offset 'content' in
/home/XXX/XXX/XXX/public_html/emailing/remote/scripts/campaigns.php
on line 73

Could you help me to find where is the problem?
Thank you.
