title: GTmetrix it is saying Serve resources from a consistent URL
body: <p>I have an issue with my Word-press site, When i tested with GTmetrix it is saying   Serve resources from a consistent URL. and it showing that i have used 2 css files one with normal correct extension .css and another one with some version extension as last which is .css?ver=4.9.8. The correct one is the first one style.css. i do not know from where the other one is coming. I have not used anywhere in my knowledge. I have tried de-activating some plugins like cache from admin panel as per Google recommendations. But it does not work. <a href="https://gtmetrix.com/reports/pentaworkspace.com/z0ra5DhP" rel="nofollow noreferrer">https://gtmetrix.com/reports/pentaworkspace.com/z0ra5DhP</a></p>
