I need to remove a code that is messing up my site!

There are a lot of places that this code could be coming from. A plugin could be loading it, your theme could be loading it or it could be hard coded into your theme code.

You can disable your plugins to see if that removes it. If it does, you can figure out which one is responsible by re-enabling them one at a time.

Otherwise you will most likely find the jquery being loaded in the functions.php file or header.php file of your theme. Based on the age of the version of Jquery that you’re loading I would wager that is is being loaded by your theme.

Hope that helps.
