Answer 1

locate the javascript file where you have your error throwing code:

$(document).ready(function(){var weatherAPI='http://api.openweathermap.org/data/2.5/weather';var data={q:"Athens",units:"metric",appid:"b0847a3de80121926a9f428c35f611f8"};function showWeather(weatherReport){var iconURL='http://openweathermap.org/img/w/'+ weatherReport.weather[0].icon+'.png';var imgE=document.createElement('img');$("#open-weather").attr('src',iconURL);$('#temperature').html('Αθήνα '+ weatherReport.main.temp+'°');}
$.getJSON(weatherAPI,data,showWeather);});;function dateAndTime(){var date=new Date();var day;var dayOfMonth=date.getDate();var month;var h=date.getHours();var m=date.getMinutes();var s=date.getSeconds();switch(date.getDay()){case 0:day="Κυριακή";break;case 1:day="Δευτέρα";break;case 2:day="Τρίτη";break;case 3:day="Τετάρτη";break;case 4:day="Πέμπτη";break;case 5:day="Παρασεκυή";break;case 6:day="Σάββατο";break;}
switch(date.getMonth()){case 0:month="Ιανουαρίου";break;case 1:month="Φεβρουαρίου";break;case 2:month="Μαρτίου";break;case 3:month="Απριλίου";break;case 4:month="Μαϊου";break;case 5:month="Ιουνίου";break;case 6:month="Ιουλίου";break;case 7:month="Αυγούστου";break;case 8:month="Σεπτεμβρίου";break;case 9:month="Οκτωβρίου";break;case 10:month="Νοεμβρίου";break;case 11:month="Δεκεμβρίου";break;}
if(h<10){h="0"+ h;}
if(m<10){m="0"+ m;}
if(s<10){s="0"+ s;}
var time=h+":"+ m+":"+ s;$('#time-now').html(time);setTimeout('dateAndTime();','1000');var myDate=day+', '+ dayOfMonth+" "+ month;$('#date-now').html(myDate);return true;};

then wrap it with

(function($) {
..
})(jQuery);

or replace the $ sign with jQuery
