Title: Failing to load resources when optimizing JS code Last modified: August 31, 2016 --- # Failing to load resources when optimizing JS code * Resolved [boybawang](https://wordpress.org/support/users/boybawang/) * (@boybawang) * [10 years, 1 month ago](https://wordpress.org/support/topic/failing-to-load-resources-when-optimizing-js-code/) * Hello – * Let me start by saying I love your plugin! * When I have “Optimize Javascript Code” enabled, some of my pages that run a certain plugin don’t work correctly. I went into “developer tools” within chrome, and noticed this: * ``` http://www.skipthedrive.com/wp-content/cache/autoptimize/js/shims/styles/shim.css Failed to load resource: the server responded with a status of 404 (Not Found) http://www.skipthedrive.com/wp-content/cache/autoptimize/js/shims/form-core.js Failed to load resource: the server responded with a status of 404 (Not Found) ``` * I tried adding jquery.js to the comma separated list of scripts to exclude, but that didn’t work. * I’m also using CometCache (formerly ZenCache). I disabled that plugin, but still had problems. * Any suggestions? * Thanks * [https://wordpress.org/plugins/autoptimize/](https://wordpress.org/plugins/autoptimize/) Viewing 11 replies - 1 through 11 (of 11 total) * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [10 years, 1 month ago](https://wordpress.org/support/topic/failing-to-load-resources-when-optimizing-js-code/#post-7198216) * now as far as the error is concerned: AO never stores files directly in the cache directory, but aggregates the files and saves them as “autoptimize_xyz.js or autoptimize_123.css”. this means that the files are being loaded by some javascript in a manner that assumes those files (shim.css and form-core.js) are in the same directory. as that js itself is optimized, the 2 files are not in the same location any more and you get those 404’s. * after some looking around it seems it is caldera forms doing this, and more specifically` caldera-forms/assets/js/polyfiller.min.js`. try excluding that from JS optimization first, but chances are you’ll have to exclude `/caldera-forms/` entirely and maybe `jquery.js` as well. * oh and do disable comet cache’s JS and CSS optimization first when using AO, using two minifiers at the same time is asking for trouble 🙂 * hope this helps, frank * Thread Starter [boybawang](https://wordpress.org/support/users/boybawang/) * (@boybawang) * [10 years, 1 month ago](https://wordpress.org/support/topic/failing-to-load-resources-when-optimizing-js-code/#post-7198316) * Hi Frank – * Thanks for the quick (and thorough) response. Excluding polyfiller.min.js did the trick! * Leaving a great review now 🙂 * Best, Pete * [oga23](https://wordpress.org/support/users/oga23/) * (@oga23) * [9 years, 7 months ago](https://wordpress.org/support/topic/failing-to-load-resources-when-optimizing-js-code/#post-8244533) * hi, i am having the same problem. Excluding the polyfiller helped with the majority of forms, but one is still not working and i don’t know why. * Please help? * Link to page: [http://mojzastopnik.si/zavarovanja/zivljenjsko-zavarovanje/osebni-konfigurator/](http://mojzastopnik.si/zavarovanja/zivljenjsko-zavarovanje/osebni-konfigurator/) The button isn’t working so nobody can enter the form, the background image should be full screen and with an overlay… * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [9 years, 7 months ago](https://wordpress.org/support/topic/failing-to-load-resources-when-optimizing-js-code/#post-8244582) * this is a difficult one; you have a script template; * ``` ``` * as that template has a `` tag, AO incorrectly injects the autoptimized JS at that place, rendering it useless (and probably killing the template as well). * try this code to force AO to inject the JS elsewhere; * ``` add_filter('autoptimize_filter_js_replacetag','oga_js_replacetag',10,1); function oga_js_replacetag($replacetag) { return array("","after"); } ``` * hope this helps, frank * [oga23](https://wordpress.org/support/users/oga23/) * (@oga23) * [9 years, 7 months ago](https://wordpress.org/support/topic/failing-to-load-resources-when-optimizing-js-code/#post-8244610) * hi! thanks for the supersonic reply! * yes, it is the body tag that is causing the problem. i removed it and is working. But… since the exclamation point is kind of essential for the form,please provide me some guidens where to put that code 🙂 * Thank you. * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [9 years, 7 months ago](https://wordpress.org/support/topic/failing-to-load-resources-when-optimizing-js-code/#post-8244617) * you can use [the code snippets plugin](https://wordpress.org/plugins/code-snippets/) to add the … code snippet I provided 🙂 * [oga23](https://wordpress.org/support/users/oga23/) * (@oga23) * [9 years, 7 months ago](https://wordpress.org/support/topic/failing-to-load-resources-when-optimizing-js-code/#post-8244619) * correction…the bacground image is showing as it supposed to, but the button isn’t working when the tag removed… * any ideas? * thanks * [oga23](https://wordpress.org/support/users/oga23/) * (@oga23) * [9 years, 7 months ago](https://wordpress.org/support/topic/failing-to-load-resources-when-optimizing-js-code/#post-8244633) * so the functions.php it is 🙂 i have to many plugins already so i just put the code in my child theme functions.php. * But…the button is still not working so it should be something more that is bothering my form. * What about the excludes js’s? * i was experimenting and added all of these: caldera-forms/assets/js/handlebars. baldrick.js, caldera-forms/assets/js/handlebars.js, caldera-forms/assets/js/polyfiller. min.js, caldera-forms/assets/js/modals.baldrick.js, caldera-forms/assets/js/jquery. form-validator.min.js, caldera-forms/assets/js/jquery.form-validator.js, caldera- forms/assets/js/caldera-modals.min.js, caldera-forms/assets/js/caldera-modals. js, caldera-forms/assets/js/frontend-script-init.min.js, caldera-forms/assets/ js/frontend-script-init.js, caldera-forms/assets/js/html5.js, caldera-forms/assets/ js/ajax-core.min.js, caldera-forms/assets/js/ajax-core.js * 🙂 * i guess that is not right either… 🙂 * thank you for your help. * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [9 years, 7 months ago](https://wordpress.org/support/topic/failing-to-load-resources-when-optimizing-js-code/#post-8244676) * well, you could try removing all excludes (except if you’re sure you need them) OR add `js/jquery/jquery.js` to the list (as you have “ReferenceError: jQuery is not defined”) * frank * [oga23](https://wordpress.org/support/users/oga23/) * (@oga23) * [9 years, 7 months ago](https://wordpress.org/support/topic/failing-to-load-resources-when-optimizing-js-code/#post-8244753) * well, i’m not sure of everything since i don’t know anything about this, really 🙂 * but – i added js/jquery/jquery.js and everything is fine now!!! * thank you thank you thank you thank you thank you !!!! * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [9 years, 7 months ago](https://wordpress.org/support/topic/failing-to-load-resources-when-optimizing-js-code/#post-8245787) * super! 🙂 Viewing 11 replies - 1 through 11 (of 11 total) The topic ‘Failing to load resources when optimizing JS code’ is closed to new replies. * ![](https://ps.w.org/autoptimize/assets/icon-256X256.png?rev=2211608) * [Autoptimize](https://wordpress.org/plugins/autoptimize/) * [Frequently Asked Questions](https://wordpress.org/plugins/autoptimize/#faq) * [Support Threads](https://wordpress.org/support/plugin/autoptimize/) * [Active Topics](https://wordpress.org/support/plugin/autoptimize/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/autoptimize/unresolved/) * [Reviews](https://wordpress.org/support/plugin/autoptimize/reviews/) ## Tags * [Failed](https://wordpress.org/support/topic-tag/failed/) * [javascript](https://wordpress.org/support/topic-tag/javascript/) * [js](https://wordpress.org/support/topic-tag/js/) * [load](https://wordpress.org/support/topic-tag/load/) * 11 replies * 3 participants * Last reply from: [Frank Goossens](https://wordpress.org/support/users/futtta/) * Last activity: [9 years, 7 months ago](https://wordpress.org/support/topic/failing-to-load-resources-when-optimizing-js-code/#post-8245787) * Status: resolved
