But the story continues...
I copied all Publisher 1.06 files to my production server (php 5.6.38-0+deb8u1). I clicked the "modules" tab in the admin. Immediately, a http 500 error occurred. So, I could'n't even update the publisher module in the module admin. Furthermore, I could not enter the admin at all after copying the 1.06 files !.
So, I copied the 1.05 files from my backup to my production server and everything worked again normally.
Can I upgrade to 1.06 on php 5.6.38 before my ISP will switch to php 7 ? Is it normal that the upgrade cannot be performed with php 5.6 ??
