If all else fails, you could always disable autoptimization of your homepage using the API (autoptimize_filter_noptimize, cfr. example code in [autoptimize_helper.php_example](http://plugins.svn.wordpress.org/autoptimize/trunk/autoptimize_helper.php_example)). * That being said; if you can provide me with the URL of your site (with AO active), I’ll be happy to take a look there myself to see what is happening. * Kind regards, frank * Thread Starter [hydro22](https://wordpress.org/support/users/hydro22/) * (@hydro22) * [10 years, 10 months ago](https://wordpress.org/support/topic/problems-with-423/#post-6361020) * [ Klick ao active But please hurry up 🙂 * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [10 years, 10 months ago](https://wordpress.org/support/topic/problems-with-423/#post-6361022) * OK, had a look and even compared with the non-AO’ed version (adding ?ao_noptimize =1) and can’t see a problem? * what do you see, can you describe what is wrong? * frank * Thread Starter [hydro22](https://wordpress.org/support/users/hydro22/) * (@hydro22) * [10 years, 10 months ago](https://wordpress.org/support/topic/problems-with-423/#post-6361023) * Yes, on all iphones an ipads with safari neither the normal pages nor the galleries are shown correctly.

The most likely culprit is JS optimization, so I would start with disabling that and see if the problem goes away. If it does, you can start playing with the JS optimization options (“force into head” for starters and if that does not work excluding specific scripts from optimization) to fix this. * frank * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [10 years, 10 months ago](https://wordpress.org/support/topic/problems-with-423/#post-6361027) * ok, saw the screenshot; the problem is not with JS, but with CSS optimization. can you briefly re-enable AO? * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [10 years, 10 months ago](https://wordpress.org/support/topic/problems-with-423/#post-6361031) * Will be offline soon now, but will be briefly/ intermittently back later tonight. * Based on the screenshot the CSS isn’t loaded, so what I would do if I were you; 0. check/ make sure this is not a caching issue (on iphone/ ipad or on your server or …) 1. look at your server’s http-logs, finding the requests for the page. are there requests for the autoptimized CSS? what status code? 2. if you know how, enable remote debugging on iOS and try to find out why the CSS is not loaded. * and for possible solutions/ workarounds/ 1. disable CSS optimization to see if the problem goes away. 2. if so, look at how CSS optimization is configured and play around with that; if you are using “inline & defer” disable that and try with “inline all CSS”. 3. if this still does not work, try excluding your CSS-files one after the other, trying to identify which one is breaking the optimized CSS * frank Viewing 8 replies - 1 through 8 (of 8 total) The topic ‘Problems with 4.2.3’ 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/) * 8 replies * 2 participants * Last reply from: [Frank Goossens](https://wordpress.org/support/users/futtta/) * Last activity: [10 years, 10 months ago](https://wordpress.org/support/topic/problems-with-423/#post-6361031) * Status: not resolved
