Currency issue

Hi, I change the PHP Version to 7.0 and work for me.

I agree with adriano, setting up version 7+ also worked for me. 

You may need to set your "locale" settings in the database to the right language ("dutch" in my case).
Go to your index.php file and add the following line just underneath the define for "minimum supported PHP version":

/* Set locale to Dutch */
setlocale (LC_TIME, "Dutch");

Problem solved!
