Title: Duplicate Autoptimize CSS Last modified: January 18, 2021 --- # Duplicate Autoptimize CSS * Resolved [Mark](https://wordpress.org/support/users/markob17/) * (@markob17) * [5 years, 4 months ago](https://wordpress.org/support/topic/duplicate-autoptimize-css/) * Hi, * When running a Gtmetrix and Webpagetest on my site, I notice two identical Autoptimize css files. Seems to be loading twice and slowing my site down a bit. I can’t seem to figure out why. Any ideas? * Regards, * Mark * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fduplicate-autoptimize-css%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 13 replies - 1 through 13 (of 13 total) * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [5 years, 4 months ago](https://wordpress.org/support/topic/duplicate-autoptimize-css/#post-13924154) * I can see the 2nd request for the same CSS-file in the network tab of both Firefox and Chrome but when inspecting the HTML source the file is referred to only once. So a very weird thing happening here .. * What happens if you disable “aggregate CSS”, are all CSS-files requested 2 times? Or if you disable “optimize CSS” as a whole? * Thread Starter [Mark](https://wordpress.org/support/users/markob17/) * (@markob17) * [5 years, 4 months ago](https://wordpress.org/support/topic/duplicate-autoptimize-css/#post-13928002) * Tried both suggestions and all CSS files are only requested once. Perhaps it is the way my theme is outputting CSS. I use a popular theme called BIMBER and it’s pretty loaded. My other site with the exact same WP-Supercache and Autoptimize settings on the same server, only shows one autoptomize CSS file. It is using GeneratePress theme. So perhaps it is my theme. Not sure why, though… Any ideas? Any insight is much appreciated. * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [5 years, 4 months ago](https://wordpress.org/support/topic/duplicate-autoptimize-css/#post-13928151) * No idea I’m afraid, as indeed the CSS-file is only referenced once in the HTML.. Could indeed be a theme (or plugin) thing, if feasible you could briefly switch themes and/ or disable (and re-enable) one plugin at a time to see if you can identify a culprit? * Thread Starter [Mark](https://wordpress.org/support/users/markob17/) * (@markob17) * [5 years, 4 months ago](https://wordpress.org/support/topic/duplicate-autoptimize-css/#post-13928189) * I will experiment some more and see if I can figure anything out. Definitely weird, but yeah, likely a theme or plugin thing. I think a theme thing since I have another site using same theme with same issue. Maybe I will ask the theme editor once I renew my subscription to them. In the meantime, if I figure anything else out, I will update this thread.

I did not. I think it may be the way the theme is generating dynamic css. * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [5 years, 3 months ago](https://wordpress.org/support/topic/duplicate-autoptimize-css/#post-14048751) * Does the problem go away when (briefly) switching themes? * Thread Starter [Mark](https://wordpress.org/support/users/markob17/) * (@markob17) * [5 years, 3 months ago](https://wordpress.org/support/topic/duplicate-autoptimize-css/#post-14049870) * [@optimizingmatters](https://wordpress.org/support/users/optimizingmatters/) I’m not sure. We didn’t test but we do have other sites on same server using different theme and there is no double CSS. * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [5 years, 3 months ago](https://wordpress.org/support/topic/duplicate-autoptimize-css/#post-14049933) * Well, that seems to point to the theme indeed, maybe contact the developers? * Thread Starter [Mark](https://wordpress.org/support/users/markob17/) * (@markob17) * [5 years, 3 months ago](https://wordpress.org/support/topic/duplicate-autoptimize-css/#post-14050133) * [@optimizingmatters](https://wordpress.org/support/users/optimizingmatters/) Yeah, we need to renew our license in order to do so and will do that eventually. The theme is pretty popular – called Bimber. My guess is the coding of the theme. * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [5 years, 3 months ago](https://wordpress.org/support/topic/duplicate-autoptimize-css/#post-14077899) * will close the topic as resolved, but don’t hesitate to add any additional info once you’re able to get feedback from the theme developers markob17 * frank * Thread Starter [Mark](https://wordpress.org/support/users/markob17/) * (@markob17) * [5 years, 3 months ago](https://wordpress.org/support/topic/duplicate-autoptimize-css/#post-14082566) * [@optimizingmatters](https://wordpress.org/support/users/optimizingmatters/) Thank you for all your help! * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [5 years, 3 months ago](https://wordpress.org/support/topic/duplicate-autoptimize-css/#post-14082624) * you’re welcome Mark 🙂 Viewing 13 replies - 1 through 13 (of 13 total) The topic ‘Duplicate Autoptimize CSS’ 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 * [css](https://wordpress.org/support/topic-tag/css/) * 13 replies * 2 participants * Last reply from: [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * Last activity: [5 years, 3 months ago](https://wordpress.org/support/topic/duplicate-autoptimize-css/#post-14082624) * Status: resolved
