Title: Optimize JavaScript Code breaks site since update Last modified: August 31, 2016 --- # Optimize JavaScript Code breaks site since update * [bcr8tive](https://wordpress.org/support/users/bcr8tive/) * (@bcr8tive) * [10 years, 1 month ago](https://wordpress.org/support/topic/optimize-javascript-code-breaks-site-since-update/) * Hi, * I discovered since the update that my posts had huge (arbitrary) gaps between them. So I set about finding the problem – and finally did. * When I have the option “Optimize JavaScript Code?” checked – the gaps are there– when I disable it, it goes away. The plugin worked great, WITH Javascript code enabled – AND helped my page speed, now it doesn’t and I have no idea what is doing what between the plugin and my theme – or if this is also something to do with the new “caching” option – I already have a cache plugin – * Here’s an example of the site with the gap (I currently have the option disabled so that isn’t displaying until I can work it out) * Here is a screenshot of the site with the gap: [http://lrhcreative.com/misc-imgs/gaps.jpg](http://lrhcreative.com/misc-imgs/gaps.jpg) * Here is my site: [bcr8tive.com](http://bcr8tive.com/) * [https://wordpress.org/plugins/autoptimize/](https://wordpress.org/plugins/autoptimize/) Viewing 15 replies - 16 through 30 (of 34 total) [←](https://wordpress.org/support/topic/optimize-javascript-code-breaks-site-since-update/?output_format=md) [1](https://wordpress.org/support/topic/optimize-javascript-code-breaks-site-since-update/?output_format=md) 2 [3](https://wordpress.org/support/topic/optimize-javascript-code-breaks-site-since-update/page/3/?output_format=md) [→](https://wordpress.org/support/topic/optimize-javascript-code-breaks-site-since-update/page/3/?output_format=md) * Thread Starter [bcr8tive](https://wordpress.org/support/users/bcr8tive/) * (@bcr8tive) * [10 years, 1 month ago](https://wordpress.org/support/topic/optimize-javascript-code-breaks-site-since-update/page/2/#post-7175564) * I’ll try sussing out the bug you saw now – * I’ve opened up your area if you want to try accessing the site again [bcr8tive.com](http://bcr8tive.com/) * Thanks Frank * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [10 years, 1 month ago](https://wordpress.org/support/topic/optimize-javascript-code-breaks-site-since-update/page/2/#post-7175565) * no luck, still blocked. can you open up for an ip-range; 178.51.*.*?
