: Why is there a DNS lookup from Bootstrap CDN that is no longer installed on my site? I am having a BIG problem. Most of the DNS lookups are suppose to be on the following site: http://gtmetrix.com/reports/ytadvisers.com/6

I figured it out, it was the speed booster pack plugin. The remove extra Font Awesome was on, turned off and everything was fine.

In this situations, this is what I will do,

login to the server using ssh, and goto wordpress installation directory, and use the following command to find out in which file the cnd link is used,

grep 'netdna.bootstrapcdn.com' -lr wp-content


So from the file list you will know from which plugin or theme the link is added.

If above command doesn't return any file, then it must be coming either from cache or from database. But it is very unlikely to come from database when the plugin is un-installed.

Edit:
In case you cannot login using ssh, add a simple php file in wordpress directory and add the following code in it,

<?php
echo exec("grep 'netdna.bootstrapcdn.com' -lr wp-content");
?>
