Title: Java Script Breaks after activating Autoptimise Last modified: September 16, 2017 --- # Java Script Breaks after activating Autoptimise * Resolved [espressotrans](https://wordpress.org/support/users/espressotrans/) * (@espressotrans) * [8 years, 6 months ago](https://wordpress.org/support/topic/java-script-breaks-after-activating-autoptimise/) * Hi there, I love Autoptimise and I would like to use it. However, when I activate the java script optimisation, both the reviews carusel and the 3 blog posts at the bottom break. * I have tried to follow all instructions found on the FAQ page but nothing….The only thing I have’t tried is exclude the 2 script but I don’t know how to find them * Is there anyone that could help me? * Thanks, Dan * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fjava-script-breaks-after-activating-autoptimise%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 12 replies - 1 through 12 (of 12 total) * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [8 years, 6 months ago](https://wordpress.org/support/topic/java-script-breaks-after-activating-autoptimise/#post-9502019) * you don’t seem to have autoptimize active now Dan; your CSS is minified with another tool? * [froscinsky](https://wordpress.org/support/users/froscinsky/) * (@froscinsky) * [8 years, 6 months ago](https://wordpress.org/support/topic/java-script-breaks-after-activating-autoptimise/#post-9502488) * I have the same problem. After activating the javascript optimization my plugins stopped working. I tried to disable all options and the plugin itself, but the problem remains and I can not restore the page to its initial state. - This reply was modified 8 years, 6 months ago by [froscinsky](https://wordpress.org/support/users/froscinsky/). - This reply was modified 8 years, 6 months ago by [froscinsky](https://wordpress.org/support/users/froscinsky/). * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [8 years, 6 months ago](https://wordpress.org/support/topic/java-script-breaks-after-activating-autoptimise/#post-9502747) * [@froscinsky](https://wordpress.org/support/users/froscinsky/); I looked at your site and Autoptimize is not active any more so any problem is unrelated to AO. But I indeed see several JS-errors, which you’ll need to solve before thinking about optimization. Once you’re there, [have a look at AO’s FAQ](https://wordpress.org/plugins/autoptimize/faq) for troubleshooting tips (every problem is fixable, given the right configuration) 🙂 * Thread Starter [espressotrans](https://wordpress.org/support/users/espressotrans/) * (@espressotrans) * [8 years, 6 months ago](https://wordpress.org/support/topic/java-script-breaks-after-activating-autoptimise/#post-9505727) * Hi, * I have just activated it.

I’m glad you got this sorted, but I wanted to jump in with a note. * There are often problems when our already minified JavaScript is minified again. That is why we have the caldera_forms_render_assets_minify filter. It prevents JavaScript and CSS from being loaded minified and combined by Caldera Forms. If that filter is used and returns false, an optimization plugin such as auto- optimize will get unminifed JS and CSS that it can then optimize accordingly. * [https://calderaforms.com/doc/caldera_forms_render_assets_minify/](https://calderaforms.com/doc/caldera_forms_render_assets_minify/) * Here is pseudo-code for how this could be done automatically. I don’t have enough knowledge of Auto-optimize to know how to finish it. But it seems like it would be a good thing to add to Auto-optimize to prevent this type of ticket – [https://pastebin.com/Picrh1yZ](https://pastebin.com/Picrh1yZ) * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [8 years, 6 months ago](https://wordpress.org/support/topic/java-script-breaks-after-activating-autoptimise/#post-9507347) * nice [@shelob9](https://wordpress.org/support/users/shelob9/), let’s cooperate on this! can you contact me via futtta-at-gmail-dot-com ? * [Josh Pollock](https://wordpress.org/support/users/shelob9/) * (@shelob9) * [8 years, 6 months ago](https://wordpress.org/support/topic/java-script-breaks-after-activating-autoptimise/#post-9510103) * Sent.
