Well, in a form I'm using the datepicker widget from kartik, which in localhost works perfect, but when I uploaded it to the server, it throws me the error that the date format is invalid.
In localhost I use MariaDB (Version: 10.1.9-MariaDB) that comes with the xampp 3.2.2, in windows 10 On the MariaDB server also on Debian 9
Apparently it must be some configuration somewhere I do not know where it is.
How could I solve this problem?
