Wordpress LScache Plugin: AFTER LAST UPDATE upstream sent too big header while reading response header f
Last Updated on: Wed, 15 Apr 2026 00:00:02 Ive just updated to the last version of LiteSpeed Cache and my pages started returning 502 Bad Gateway addons. Ive checked my error log and it gave me upstream sent too big header while reading response header from upstream . The problem was gone when I disabled the LiteSpeed Cache plugin The same issue here, the page loading time has increased from 7sec up to 30 sec after update. Hi, May I know what is your server set up ? Best regards, This is related to the new CCSS service. Will improve in a short time Do you have CCSS ON and CCSS background generation OFF? Hi, Would you please join our Slack community ? We will need some further information to debug this Please let me know your username in Slack so we can contact you. Best regards, I have CCSS and CCSS Background Generation turned on. I tried turning them off but the result was the same. Ive joined your Slack group, user ? James Walker The new version has created errror. No CSS cache is on, but the page speed is reduced drastically https://gtmetrix.com/reports/iqmstore.com/cbbtqts6 @scandinaviannerd Is your Critical CSS on? Hi, @scandinaviannerd I will mark this topic as lack of activity , please create your own topic if you still have problem with CCSS. Best regards,
