Title: Jquery: render blocking error VS not defined Last modified: May 22, 2019 --- # Jquery: render blocking error VS not defined * Resolved [outcats85](https://wordpress.org/support/users/outcats85/) * (@outcats85) * [7 years, 1 month ago](https://wordpress.org/support/topic/jquery-render-blocking-error-vs-not-defined/) * If I remove the jquery.js to the Exclude scripts from Autoptimize list, Jquery becomes a render blocking script. If I add it to the list I get rid of the error on Google but then I get this error on Chrome Console instead when loading the page: Uncaught ReferenceError: jQuery is not defined at Autoptimize_single_e4c886b4345291d5682832373e8c720a. js?ver=1.0.0:1 * Any way to remove both errors? I also have the “Aggregate all linked JS-files to have them loaded non-render blocking? If this option is off, the individual JS-files will remain in place but will be minified” and ” Let Autoptimize also extract JS from the HTML. Warning: this can make Autoptimize’s cache size grow quickly, so only enable this if you know what you’re doing” enabled. * Thanks. * By the way after the latest Google Speed Test update my score went down from 90/100 to 35/100. Freaking unbelievable. It says that it takes up to 10 seconds( sometimes) to load the page when actually in Pingdom it takes about 100ms. - This topic was modified 7 years, 1 month ago by [outcats85](https://wordpress.org/support/users/outcats85/). * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fjquery-render-blocking-error-vs-not-defined%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 6 replies - 1 through 6 (of 6 total) * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [7 years, 1 month ago](https://wordpress.org/support/topic/jquery-render-blocking-error-vs-not-defined/#post-11558133) * The best solution is to move away from plugins that require jQuery early (I think in your case it’s wpvr). * Other then that you could try [the code snippet at in this blogpost](https://blog.futtta.be/2018/12/13/how-to-fix-render-blocking-jquery-js-in-autoptimize/), but that’s not a guaranteed working fix for all possible cases. * hope this helps, frank * Thread Starter [outcats85](https://wordpress.org/support/users/outcats85/) * (@outcats85) * [7 years, 1 month ago](https://wordpress.org/support/topic/jquery-render-blocking-error-vs-not-defined/#post-11558426) * Thanks. Should I just copy the code like that in the function.php file without editing anything? Disabling the plugin did work. Trying to find a solution to keep the plugin active though. - This reply was modified 7 years, 1 month ago by [outcats85](https://wordpress.org/support/users/outcats85/). - This reply was modified 7 years, 1 month ago by [outcats85](https://wordpress.org/support/users/outcats85/). * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [7 years, 1 month ago](https://wordpress.org/support/topic/jquery-render-blocking-error-vs-not-defined/#post-11558457) * You _could_ add it to functions.php, but the safer solution could be to use [the code snippets plugin](https://wordpress.org/plugins/code-snippets/) to do so? 🙂 * Thread Starter [outcats85](https://wordpress.org/support/users/outcats85/) * (@outcats85) * [7 years, 1 month ago](https://wordpress.org/support/topic/jquery-render-blocking-error-vs-not-defined/#post-11558948) * Thanks.
