I upgraded to jquery 1.11.3 and keep the lines in this order now:
<head>
<script type="text/javascript" src="jquery-1.11.3.min.js"> </script>
<script type="text/javascript" src="show.js"> </script>
</head>
I removed one extra closing bracket from the line below right after jquery.js:
<script src="jquery.js"> type="text/javascript"></script>
so the correct line looks like this:
<script src="jquery.js" type="text/javascript"></script>
However, that did not help. The trick was in my other scripts' order. That is I reversed the order I had and it started to work. For example I had script1, script2, script3 placed like this:
<script src="script1.js"> type="text/javascript"></script>
<script src="script2.js"> type="text/javascript"></script>
<script src="script3.js"> type="text/javascript"></script>
Now I have changed it to:
<script src="script1.js"> type="text/javascript"></script>
<script src="script3.js"> type="text/javascript"></script>
<script src="script2.js"> type="text/javascript"></script>
and it all revived. Hope it will help someone out there. Make sure you check / experiment with your scripts' places and chances are it will work for your as well. Just remember it all has to go coherently and successively.
