# Cached CSS usurping theme settings??

 * This plugin has worked great for our site for a few years now. However, once 
   we upgraded to WP 5.9 and auto-updated all plugins, I had this very weird orange
   color start popping up all over the place (on buttons, links, text, etc.)
 * I have looked through every conceivable color setting and no where is this orange
   color indicated.
 * Finally, I used Firefox web developer tool to try and track down where this is
   coming from. It is showing me the “offending” style sheet is located:
 * wp-content/cache/autoptimize/css/autoptimize_single_c7b47dfe51189fcd29c00ab535849f5f.
   css
 * After googling around I stumbled on the blog entry you did noting these cached
   style sheets were a known problem that had been fixed. Thinking maybe this was
   just an old cached version that stemmed from that issue, so I tried to delete
   them and it just recreated them (and the orange color persists).
 * Any idea where this might come from or how to modify it???
 * Thanks in advance,
 * Brent

 * ah, afraid the original CSS-file (before optimization) is /wp-content/uploads/
   hummingbird-assets/c69757b374b3b69a1d53e131c75a7a2a.css actually kapricious. 
   I would strongly suggest disabling CSS/ JS optimization in Hummingbird when using
   Autoptimize to avoid any possible conflict. If the problem persists with Hummingbird
   disabled, I’ll be happy to (try to) identify the culprit file for you 🙂
 * hope this helps,

 * Frank,
 * You are a life saver. Disabled hummingbird and everything is exactly as it should
   be. Thank you so much. How the heck did you figure that out if you don’t mind
   sharing your secrets?!?! 🙂
 * Thank you again, you’re amazing.

 * Morning Brent;
    No secrets; I view-sourced the homepage HTML, took note of the
   id in front of the file you mnetioned and then view-sourced the unoptmized HTML(
   by adding `?ao_noptimize=1` to the URL) which turned out to be the hummingbird
   one 🙂
 * feel free to [leave a review of the plugin and support here](https://wordpress.org/support/plugin/autoptimize/reviews/#new-post)!
