 * Hi Frank, I use Autoptimize on a lot of websites without problems, thanks for
   your great plugin.
 * However, I have this site, and I can’t figure out why I have jQuery problems.
   I think it’s Contact Form 7 that causes the problem, but I can’t delete it unfortunately.(
   I also use it on other sites without problems.) I’d like to use Autoptimize too…
 * Do you have any idea how to solve this?
 * Thank you,
    Annamaria

 * It looks like you have 2 versions of jQuery loading, one the stock WordPress 
   one (3.x.x) and one from [https://code.jquery.com/jquery-2.2.4.min.js](https://code.jquery.com/jquery-2.2.4.min.js).
   I *think* the 2.2.4 one is causing this, try finding out what is adding that 
   and then remove it somehow?

 * I think I found it, I contacted the developer.
 * Thanks for your help!
