Unfortunately I can’t test the plugin you’re referencing as it requires a purchase. A great plugin I often recommend that achieves this behavior is Autoptimize as it’s a fantastic plugin with a great developer (and community) behind it. * Out of the cache clearing you’ve posted above, is the Cache Enabler cache always being cleared last? Without being able to replicate the issue myself my first assumption would be Cache Enabler has a cached page that is referencing generated CSS and/or JavaScript files that no longer exist. To confirm whether or not this is the case, would it be possible to receive a screenshot of your browser’s developer console on a page where this occurs? In case you don’t know, one way to access this is by right clicking on your page, clicking on Inspect (or Inspect Element), and then navigating to the Console panel. * Thread Starter anonymized-17631918 * (@anonymized-17631918) * [5 years, 7 months ago](https://wordpress.org/support/topic/compatibility-problems-7/#post-13603848) * Hello, * Essential Addons is a free version: [https://de.wordpress.org/plugins/essential-addons-for-elementor-lite/](https://de.wordpress.org/plugins/essential-addons-for-elementor-lite/) * I also tested clearing Cache from Cache Enabler first… looks little bit better but some pages also has these Problems. I make some more tests and send you the screenshot. * Anonymous User 16850768 * (@anonymized-16850768) * [5 years, 7 months ago](https://wordpress.org/support/topic/compatibility-problems-7/#post-13603879) * Ah, I wasn’t aware that their is a free version! Thank you for pointing that out, I should have looked better. Cache Enabler should be cleared last as that will ensure the newly generated CSS and/or JavaScript files are included in the cached page. If you receive `404` errors on your generated CSS/JS files that would indicate the cached page is stale and is referencing files that no longer exist (because you cleared the cache that generated those files). * Thread Starter anonymized-17631918 * (@anonymized-17631918) * [5 years, 7 months ago](https://wordpress.org/support/topic/compatibility-problems-7/#post-13612967) * So, i make some more tests. Cache Enabler is definitely the problem. * – Without Caching is working fine – Other Caching solutions like WP-Rocket or WP Fastest Cache are working fine * I also checked for 404 errors or something else… nothing. * Looks like Cache Enabler is blocking the generation of these Assets (Elementor and Essential Addons)… not every time but very often. * Server error.log is also clean and there are no problems seen in DevConsole. * Very confusing… but at the Moment i have to use another Caching plugin. But i hope you can fix this and i can switch back to Cache Enabler. * [Matt Gibbs](https://wordpress.org/support/users/mgibbs189/) * (@mgibbs189) * [5 years, 7 months ago](https://wordpress.org/support/topic/compatibility-problems-7/#post-13630289) * @tkwpweb does downgrading to [1.4.9](https://downloads.wordpress.org/plugin/cache-enabler.1.4.9.zip) clear up issues for you? * I’ve been having trouble with the entire 1.5.x branch too, so am using 1.4.9 ( without issue) until time clears up to further troubleshoot the issue. * Thread Starter anonymized-17631918 * (@anonymized-17631918) * [5 years, 7 months ago](https://wordpress.org/support/topic/compatibility-problems-7/#post-13630356) * Thank you! 1.4.9 works fine. I did 10 tests and all were fine. * Thread Starter anonymized-17631918 * (@anonymized-17631918) * [5 years, 7 months ago](https://wordpress.org/support/topic/compatibility-problems-7/#post-13633538) * Another good solution is to exclude the “/wp-content/uploads/” folder if you use any CSS/JS optimize plugins like Autoptimize or Fast Velocity Minify. * This also reduce the “error-times”.
