Latest plugin breaks our website

Hey @xxjergerxx

I’ve checked your site and here is what I’ve found:
1. You are loading the jQuery twice. From the core and there is an additional jquery script in your theme header.php file. This is not recommended, so please remove the one from your header.
2. You are lazyloading the jQuery file from the core using the “Async JavaScript” plugin. This is not recommended, because it may cause “jQuery undefined” errors. There are a lot of inline scripts that rely on jQuery to be loaded on the page load.
3. Our combined script is not lazyloaded, but it also uses jQuery, and when it’s loaded after all other scripts, an error is thrown.

Here is what you should do in order to use the Combine JS functionality:
1. Remove the additional jQuery library
2. Disable jQuery lazyloading or enable “Defer Render-blocking JS” functionality in our plugin.

Defer hurts the scoring vs async and causes web browser compatibility issues with their slide show plugin. I can ask/ test.

I believe it causes it to not load on some mobile devices and safari (defer) or harms the site page speed, I can test it once the developer takes a look.

Do you guys plan on implementing async?

I disabled async plugin and re-enabled the SG Optimizer features including DEFER, it no longer appears to be breaking the site.

Are you able to pinpoint which of the three need to be removed in the header?
<script src=”https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js”></script&gt;
<script src=”<?php echo site_url(); ?>/test/wp-content/themes/OutlandsTheme/js/script.js”></script>
<script src=”<?php echo site_url(); ?>/test/wp-content/themes/OutlandsTheme/js/script_download.js”></script>

Removing this breaks the slideshow at the top:

<script src=”https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js%22%3E</script&gt;

I think at this point the plugin is working fine and your case is closed. We will need the developer to retire the slide show then the extra jquery:)

Generally, that’s the best thing to do. Meanwhile, you can try this so you don’t have broken parts on live sites: https://www.ads-software.com/plugins/enable-jquery-migrate-helper/
