Hello,
The solution is very easy but we needed to know your license to suggest the line to be changed.
As you're using a PRO license, please edit the classes/CreateText.inc file and replace this (around line 444):
if (empty($texts['text'])) {
$texts['text'] = '';
}
by:
if (!isset($texts['text'])) {
$texts['text'] = '';
}
This change solves your issue.
Regards.
