    Some research...

    Your error was,

    Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP

    Type "methods same name as class php" into google and the first two results are Stack Overflow questions, with lots of info for you.

    The third result is http://php.net/manual/en/language.oop5.decon.php. Always worth reading what php.net has to say about PHP. Click on Google's link and scroll a little way down to find...

    For backwards compatibility with PHP 3 and 4, if PHP cannot find a __construct() function for a given class, and the class did not inherit one from a parent class, it will search for the old-style constructor function, by the name of the class.

    and...

    Warning Old style constructors are DEPRECATED in PHP 7.0, and will be removed in a future version. You should always use __construct() in new code.


    The conclusion...

    From that research we can work out that you need to do a quick update in your code. Replace the line,

    function qwis_facebook_widget() {
    

    with

    function __construct() {
