Great, thanks Jan.
Yet, my provider is still in the process of testing php version 7 and they will migrate before the end of this year as support ends for php version 5.6 at 31-12-2018.
While waiting for the migration to come any time soon, I'll give the older version a try and see what it does.
I then will have to upgrade/migrate to the newer version later on.
Assumption causes many times lots of trouble.
