Are you using PHP 5.6 or higher?

[Thadr]

Yes, the server is using PHP 5.6.3, and mysql (10.0.30-MariaDB)

[Thadr]

I had my hosting provider install PHP 7.0 and the error is now gone.

PHP 5.6 should have been sufficient. Will look into it deeper to see if I can recreate it. I am glad it is working for you.
