There are 3 icons facebook, linkedin, twitter. Linkedin and twitter show perfectly even with hover, However, with the facebook one, the default isnt showing only if you hover over the text FACEBOOK. then it shows the hover

Hi,

See the second row of your styling here:

#topnavi{ width:1048px;height:100px; margin:0px auto; padding:14px 0px;}
    `
#topnavi .btn1 a{float:left; width:64px; height:67px; display:block; background-image:url(http://www.jagmit.co.uk/wp-content/themes/jag/images/social/facebook.png); background-repeat:no-repeat; text-indent:-9999px; outline:none; margin:0px 40px 0px 0px;}

There's a little apostrophe typo thing there, remove it and it should work.
