Title: jQuery is not defined – javascript error Last modified: August 22, 2016 --- # jQuery is not defined – javascript error * [juniorbra](https://wordpress.org/support/users/juniorbra/) * (@juniorbra) * [11 years, 7 months ago](https://wordpress.org/support/topic/jquery-is-not-defined-javascript-error/) * Hi, * My site is showing several javascript errors, specially “jQuery is not defined” as you can see in the new relic print [http://goo.gl/pJGvx9](http://goo.gl/pJGvx9) and in the browser console report [http://goo.gl/Pjckpb](http://goo.gl/Pjckpb) * Basically I ran google page insights and added all the javascript and CSS blocking codes to Minify section, as you can see here [http://goo.gl/ZRWCi4](http://goo.gl/ZRWCi4) and here [http://goo.gl/0ZKOYq](http://goo.gl/0ZKOYq) respectively. * Is there something I can do to fix these javascript errors? * Thanks! * [https://wordpress.org/plugins/w3-total-cache/](https://wordpress.org/plugins/w3-total-cache/) Viewing 4 replies - 1 through 4 (of 4 total) * Thread Starter [juniorbra](https://wordpress.org/support/users/juniorbra/) * (@juniorbra) * [11 years, 7 months ago](https://wordpress.org/support/topic/jquery-is-not-defined-javascript-error/#post-5349666) * Update: After disabling minify JS in W3TC and enabling it in Cloudflare the number of errors dropped a lot [http://goo.gl/6QdnXK](http://goo.gl/6QdnXK) . So I a using W3TC to minify HTML and CSS, and Cloudflare to minify JS. The downside is losing 1%-2% grade in Pagespeed and YSlow 🙁 * [Ron Vis](https://wordpress.org/support/users/ronvis/) * (@ronvis) * [11 years, 7 months ago](https://wordpress.org/support/topic/jquery-is-not-defined-javascript-error/#post-5349761) * In W3TC, make sure jQuery is first in the list of JS files to be minified. * Thread Starter [juniorbra](https://wordpress.org/support/users/juniorbra/) * (@juniorbra) * [11 years, 7 months ago](https://wordpress.org/support/topic/jquery-is-not-defined-javascript-error/#post-5349762) * Yes, I guess it is 🙁 * This is the order I am using: * [http://mysite.com.br/wp-includes/js/jquery/jquery.js](http://mysite.com.br/wp-includes/js/jquery/jquery.js) [http://mysite.com.br/wp-includes/js/jquery/jquery-migrate.min.js](http://mysite.com.br/wp-includes/js/jquery/jquery-migrate.min.js) [http://mysite.com.br/wp-content/plugins/optin-monster/assets/js/api.js](http://mysite.com.br/wp-content/plugins/optin-monster/assets/js/api.js) [http://mysite.com.br/wp-content/plugins/mashsharer/assets/js/mashsb.min.js](http://mysite.com.br/wp-content/plugins/mashsharer/assets/js/mashsb.min.js) [http://mysite.com.br/wp-content/plugins/mashshare-google-analytics/assets/js/mashga.min.js](http://mysite.com.br/wp-content/plugins/mashshare-google-analytics/assets/js/mashga.min.js) [http://mysite.com.br/wp-content/plugins/mashshare-networks/assets/js/mashnet.min.js](http://mysite.com.br/wp-content/plugins/mashshare-networks/assets/js/mashnet.min.js) * [AJ @ WpFASTER.org](https://wordpress.org/support/users/ajm_1976/) * (@ajm_1976) * [11 years, 7 months ago](https://wordpress.org/support/topic/jquery-is-not-defined-javascript-error/#post-5349764) * Have you tried: 1.) Combining only? 2.) Combine only + Render blocking (default) i.e. no async? 3.) Combine + Minify + Render blocking (default) i.e. no async? 4.) Combining only `jquery` files and placing them in the `` and remainder at the opening ``? Or (and better yet) at the ``? 5.) Loading `jquery` from Google libraries instead? 6.) CloudFlare’s Rocket Loader? (isn’t recognized as non-blocking by Google bot but does, in fact, work for the end-user on Chrome and Firefox). * …I promise, there’s a solution and you almost certainly can find it right within W3TC. It might take a lot of A/B testing and running through all logical permutations— but it _is_ there. * You should also try disabling plugins to see which ones, if any, aren’t playing nice with W3TC’s minify directives. * Best, AJ * P.s.
