Why is there a # and other characters in URL for WordPress site?

Question

I have a WordPress site and have re-written the URL for SEO friendly URLs. But I keep getting this at the end of all pages /#.UmNDU_mnqy4.

e.g.: www.example.com/contact-us/#.UmNDU_mnqy4

Can this URL be improved so that the character # and everything after that be omitted?

I searched in Google for how to omit it but no help there. Is there any way out? I used the default WordPress theme. My plugins used are:

• Collapse-O-Matic
• Contact Form 7
• Ditty News Ticker
• Easy Image Gallery
• HW Image Widget
• Image Widget
• NextGEN Gallery by Photocrati
• TablePress
• vSlider
• WordPress Backup to Dropbox

I've also disabled each and then one by one enabled all of the plugins, but still there's these characters in the URL.

Answer 2

1. Go to admin panel, Settings, Permalinks. Set the default option, save (check if the problem was fixed), and after that set the previous option and save again.

2. Go to your .htaccess file (you can find it in the root folder, near wp-config.php) and check it for some "#" character.
