Title: CSS Issue with latest update Last modified: July 25, 2022 --- # CSS Issue with latest update * [Kingyyyy](https://wordpress.org/support/users/kingyyyy/) * (@kingyyyy) * [4 years ago](https://wordpress.org/support/topic/css-issue-with-latest-update/) * Hello, * From Rapidload support, as I was having issues with many warnings appearing on each page:- * “There is an issue in Autoptimize CSS option which makes RapidLoad to throws out warnings. We have passed this to Autoptimize support who will get back to us with a solution. Until that you could disable the CSS options in Autoptimize plugin.” * This issue only occurred with the latest updated, after I clicked the ‘permanent new conditional logic button’ you added. * Looking forward to your update.

I’ll reach out to them to hear if there’s anything on AO’s end to do. * Thread Starter [Kingyyyy](https://wordpress.org/support/users/kingyyyy/) * (@kingyyyy) * [4 years ago](https://wordpress.org/support/topic/css-issue-with-latest-update/#post-15856013) * Hello, * The option was here: [https://i.gyazo.com/4981b806d201f0ea645af84ce0669408.png](https://i.gyazo.com/4981b806d201f0ea645af84ce0669408.png) * I might have described it wrong to you, as it was in AO. * It said this logic was disabled for people who had the plugin running before version XX to help with larger/complex scripts (I’ve had AO active before the version it mentioned)- So I clicked it and then the option disappeared as it was a permeant feature in the latest update of AO. * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [4 years ago](https://wordpress.org/support/topic/css-issue-with-latest-update/#post-15856032) * Ah ok … well, you can use this filter to disable the “compatibility code” again; * ``` add_filter( 'autoptimize_filter_init_compatibility', '__return_false' ); ``` * Thread Starter [Kingyyyy](https://wordpress.org/support/users/kingyyyy/) * (@kingyyyy) * [4 years ago](https://wordpress.org/support/topic/css-issue-with-latest-update/#post-15856043) * Thanks. I’ll use this for now. * It will be great if you can discuss with RL and found a solution going forward, too, as I believe they’ve contacted you. * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [4 years ago](https://wordpress.org/support/topic/css-issue-with-latest-update/#post-15856306) * the weird thing; there’s nothing pertaining to CSS in the compatibility code, it’s all JS .. * Thread Starter [Kingyyyy](https://wordpress.org/support/users/kingyyyy/) * (@kingyyyy) * [4 years ago](https://wordpress.org/support/topic/css-issue-with-latest-update/#post-15858004) * I turned off these settings as RL instructed me to do so, and the issue is fixed for now: [https://i.gyazo.com/2922a515f429989dab6cded44aa4f68f.png](https://i.gyazo.com/2922a515f429989dab6cded44aa4f68f.png) * I had the settings on with the previous version of AO and there were no issues. * For performance reasons I’d like to have them on, though. * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [4 years ago](https://wordpress.org/support/topic/css-issue-with-latest-update/#post-15858696) * OK, so not related to the “compatibility” option after all, that makes sense 😉 * Can you try replacing autoptimize 3.1 with the previous version (which you can download from [https://downloads.wordpress.org/plugin/autoptimize.3.0.4.zip](https://downloads.wordpress.org/plugin/autoptimize.3.0.4.zip)) to confirm (or not) this is related to the latest update? * Thread Starter [Kingyyyy](https://wordpress.org/support/users/kingyyyy/) * (@kingyyyy) * [4 years ago](https://wordpress.org/support/topic/css-issue-with-latest-update/#post-15859882) * Hello, * Downgraded and enabled the CSS options, cleared all caches, and no issues at all like before. * It seems it is due to the latest update. * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [4 years ago](https://wordpress.org/support/topic/css-issue-with-latest-update/#post-15859977) * how unexpected .. any PHP errors in the PHP errorlog file? * Thread Starter [Kingyyyy](https://wordpress.org/support/users/kingyyyy/) * (@kingyyyy) * [4 years ago](https://wordpress.org/support/topic/css-issue-with-latest-update/#post-15860031) * Hello, * I only see RL errors like this in the current log and previous logs (“” for sensitive info removed):- * `[proxy_fcgi:error] [pid "some numbers":tid "some numbers"] [client "IP"] AH01071: Got error 'PHP message: WordPress database error Illegal mix of collations for operation 'UNION' for query SELECT files FROM wp_rapidload_uucss_job WHERE files IS NOT NULL UNION ALL SELECT files FROM wp_rapidload_uucss_rule WHERE files IS NOT NULL made by require('wp-blog-header.php'), require_once('wp-includes/template- loader.php'), do_action('template_redirect'), WP_Hook->do_action, WP_Hook->apply_filters, UnusedCSS_RapidLoad->uucss_notfound_fallback, UnusedCSS_DB::get_original_file_name', referer: https://""` - This reply was modified 4 years ago by [Kingyyyy](https://wordpress.org/support/users/kingyyyy/). * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [4 years ago](https://wordpress.org/support/topic/css-issue-with-latest-update/#post-15860042) * hmmm, those are RL’s but they don’t shed light on what might be going on on AO’s side. when on AO31 but with RL disabled, are CSS files aggregated as they should? * Thread Starter [Kingyyyy](https://wordpress.org/support/users/kingyyyy/) * (@kingyyyy) * [4 years ago](https://wordpress.org/support/topic/css-issue-with-latest-update/#post-15860053) * These are the options I currently have on whilst downgraded: [https://i.gyazo.com/639b16972291119962c1f722da004d61.png](https://i.gyazo.com/639b16972291119962c1f722da004d61.png) * Should I tick the 2nd box? * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [4 years ago](https://wordpress.org/support/topic/css-issue-with-latest-update/#post-15860063) * errr … what were your settings before things broke? * Thread Starter [Kingyyyy](https://wordpress.org/support/users/kingyyyy/) * (@kingyyyy) * [4 years ago](https://wordpress.org/support/topic/css-issue-with-latest-update/#post-15860072) * The same I believe.
