Title: Wizard Async JavaScript Doesn´t work Last modified: January 5, 2020 --- # Wizard Async JavaScript Doesn´t work * [pastorizag](https://wordpress.org/support/users/pastorizag/) * (@pastorizag) * [6 years, 4 months ago](https://wordpress.org/support/topic/wizard-async-javascript-doesnt-work/) * Dear: * Yesterday I installed the plugin Async JavaScript because I have problems with the speed of my page in a mobile environment. I am a beginner in wordpress and I tried to configure the plugin through Wizard. I tried to run the wizard five times but all the time the blue bar is waiting and nothing happens. I completed the user and the API of the plugin into wordpress but I do not know why not working. * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fwizard-async-javascript-doesnt-work%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 10 replies - 1 through 10 (of 10 total) * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [6 years, 4 months ago](https://wordpress.org/support/topic/wizard-async-javascript-doesnt-work/#post-12293847) * The wizard requires successful communication between your browser and your server and between your server and gtmetrix. The most likely reason it doesn’t work is a problem in the latter connection (timeouts or simply blocked), but it is very hard to confirm. Your php errorlog _might_ have info though. * But as you’ve already got Autoptimize running and as you seem to have only 1 external JS-script, you could also simply add `bestazon.io` to Autoptimize -> Extra -> Async instead. * hope this helps, frank * Thread Starter [pastorizag](https://wordpress.org/support/users/pastorizag/) * (@pastorizag) * [6 years, 4 months ago](https://wordpress.org/support/topic/wizard-async-javascript-doesnt-work/#post-12294007) * Dear Frank: * I checked php errorlog but I don´t find the error about plugin Async JavaScript.

* Another thing, You speak about add bestazon.io in Autopmitize plugin but I do not find this option. The only similar parameter is: * Archivos JavaScript asíncronos: Tienes “Async Javascript” instalado, la configuración de javascript asíncrono se realiza mejor allí. * Sorry for my questions but I am an beginner in this topics 🙁 * Thanks in advance Regards * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [6 years, 4 months ago](https://wordpress.org/support/topic/wizard-async-javascript-doesnt-work/#post-12294016) * > I checked php errorlog but I don´t find the error about plugin Async JavaScript. > The error code below: * no, doesn’t seem relevant indeed. * > Archivos JavaScript asíncronos: Tienes “Async Javascript” instalado, la configuración > de javascript asíncrono se realiza mejor allí. * disable Async JavaScript (the plugin) and at that point you’ll be able to add` bestazon.io` in Autoptimize -> Extra -> Async * Thread Starter [pastorizag](https://wordpress.org/support/users/pastorizag/) * (@pastorizag) * [6 years, 4 months ago](https://wordpress.org/support/topic/wizard-async-javascript-doesnt-work/#post-12294883) * Dear: * The support team of the server asks me the following question: * Can you contact the plugin support to indicate to which host or link the plugin is connected so that we can perform a connectivity test from your account and discard possible causes? * Thank in advance * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [6 years, 4 months ago](https://wordpress.org/support/topic/wizard-async-javascript-doesnt-work/#post-12295449) * sure, the API endpoint is `https://gtmetrix.com/api/0.1`. * Thread Starter [pastorizag](https://wordpress.org/support/users/pastorizag/) * (@pastorizag) * [6 years, 4 months ago](https://wordpress.org/support/topic/wizard-async-javascript-doesnt-work/#post-12295909) * Dear: * My host provider webempresa answered this about the conecction.
