Title: Async JavaScript Plugin Last modified: November 7, 2018 --- # Async JavaScript Plugin * [DiviUser](https://wordpress.org/support/users/specializedmedia/) * (@specializedmedia) * [7 years, 6 months ago](https://wordpress.org/support/topic/async-javascript-plugin/) * I was having intermittent trouble with my front page slider—not sliding— and my number counter—not showing (and not counting). On a second page, only the photos of the slider weren’t working—and I couldn’t figure it all out until today, when: * My PDF Embedder stopped working, so one-by-one I determined it to be an AsyncJavaScript plugin problem. Turn it off—everything is working and normal— the problem is: I want to continue to use the plugin. * I DID ‘exclude’ my ‘PDF Viewer’ within the Async plugin, but it didn’t correct the problem. * Solution to get my site running in-full: Deactivate the plugin. * Any better suggestions? * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fasync-javascript-plugin%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 11 replies - 1 through 11 (of 11 total) * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [7 years, 6 months ago](https://wordpress.org/support/topic/async-javascript-plugin/#post-10858757) * what asyncjs-configuration did you use for jquery? did you get any JS errors on the brwoser console? * Thread Starter [DiviUser](https://wordpress.org/support/users/specializedmedia/) * (@specializedmedia) * [7 years, 6 months ago](https://wordpress.org/support/topic/async-javascript-plugin/#post-10861050) * Async method chosen. * Tried a different browser with similar results.

I set to now DEFER and we are working again. * Is the plugin working at all with these non-Async settings? Should I just turn it off? * Very, very much appreciated, * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [7 years, 6 months ago](https://wordpress.org/support/topic/async-javascript-plugin/#post-10862500) * > Is the plugin working at all with these non-Async settings?

If however you’re using Autoptimize (or something similar) then your aggregated JS is probably deferred already so in that case AsyncJS is of less use to you. * hope this helps, frank * [tgoarant](https://wordpress.org/support/users/tgoarant/) * (@tgoarant) * [7 years, 6 months ago](https://wordpress.org/support/topic/async-javascript-plugin/#post-10876735) * Hello, * I am having a problem with the plugin, on my side it is not working moreover on mobile version, the homepage picture has its position change and is surrounded by a blue doted line, any suggestion? * Thanks in advance. * Thibaut * [https://www.thibautgoarant.com](https://www.thibautgoarant.com) * [tgoarant](https://wordpress.org/support/users/tgoarant/) * (@tgoarant) * [7 years, 6 months ago](https://wordpress.org/support/topic/async-javascript-plugin/#post-10876849) * [https://www.thibautgoarant.com/async-plugin-error-on-mobile/](https://www.thibautgoarant.com/async-plugin-error-on-mobile/) * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [7 years, 6 months ago](https://wordpress.org/support/topic/async-javascript-plugin/#post-10877000) * can’t access your site due to a problem with your HTTPS certificate [@tgoarant](https://wordpress.org/support/users/tgoarant/), so the only advice I can give at this moment is to check your browser’s console for JS errors + not to async or defer jQuery + try to exclude plugins from async to see if this fixes anything. * hope this helps, frank * [tgoarant](https://wordpress.org/support/users/tgoarant/) * (@tgoarant) * [7 years, 6 months ago](https://wordpress.org/support/topic/async-javascript-plugin/#post-10877057) * thanks I’ll try this, however I’m beginner so I don’t know how to check my browser’s console for JS errors… (firefox). which plugin I should exclude? I am not using autoptimize as it make my front page flickering when loading… * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [7 years, 6 months ago](https://wordpress.org/support/topic/async-javascript-plugin/#post-10877096) * re browser console see [https://codex.wordpress.org/Using_Your_Browser_to_Diagnose_JavaScript_Errors#Firefox](https://codex.wordpress.org/Using_Your_Browser_to_Diagnose_JavaScript_Errors#Firefox) * re what to exclude; not idea what you’re using and what might be causing the issues, but who not try some classic trial and error? 🙂 * [tgoarant](https://wordpress.org/support/users/tgoarant/) * (@tgoarant) * [7 years, 6 months ago](https://wordpress.org/support/topic/async-javascript-plugin/#post-10877158) * thanks, it is too complex for me, I’ll stop here, sorry for wasting your time.
