I have lots of extra letter and numbers at the end of all the site pages. If you check the website: www.rsiapparel.co.uk you will see what I mean, I get this: http://www.rsiapparel.co.uk/#sthash.4xYBB5vG.dpbs
How do I remove these bits #sthash.4xYBB5vG.dpbs?
If you hava an access to the .htaccess file you can define some rules there.
for exampele:
The [NC] flag: causes the RewriteRule to be matched in a case-insensitive manner
The [L] flag: "The [L] flag causes mod_rewrite to stop processing the rule set. In most contexts, this means that if the rule matches, no further rules will be processed."
The # is a comment
$x: that is how you match the values in the adrress to the variables
