Wordpress LScache Plugin: Litespeed cache and cookie
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hello, Sorry for my english. I often have pages with 400 errors and I just realized that they happen for example when I update an article. After seeing the different messages on the forums. It seems to be from the cookies. So I know the source of the problem, because when I go to the site in private browsing, the error doesnt come. Do you have any ideas about this cookie problem? Is it possible to make another cookie or other I have no idea. Thank you for your help. Hi @espacemusculation, do you find any error on server/php error.log or access.log when the error occurred? @stanleylitespeed Thank you for your answer. Where can I find his information? This for example ? 12/05/19 09:21:12.784 [88.191.115.4:53318 1 LTS] ------POST HTTP/1.0 (HTTPS) /admin007/admin-ajax.php 12/05/19 09:21:12.784 [88.191.115.4:53318 1 LTS] Query String: 12/05/19 09:21:12.784 [88.191.115.4:53318 1 LTS] HTTP_REFERER: https://www.docteur-fitness.com/admin007/index.php 12/05/19 09:21:12.784 [88.191.115.4:53318 1 LTS] User Agent: Mozilla/5.0 (Windows NT 10.0 Win64 x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36 12/05/19 09:21:12.784 [88.191.115.4:53318 1 LTS] Accept: / 12/05/19 09:21:12.784 [88.191.115.4:53318 1 LTS] Accept Encoding: gzip,br 12/05/19 09:21:12.784 [88.191.115.4:53318 1 LTS] Cookie _lscache_vary: logged-in:1 role:99 12/05/19 09:21:12.784 [88.191.115.4:53318 1 LTS] X-LSCACHE: false 12/05/19 09:21:12.791 [88.191.115.4:53320 1 YHP] ------POST HTTP/1.0 (HTTPS) /admin007/admin-ajax.php 12/05/19 09:21:12.791 [88.191.115.4:53320 1 YHP] Query String: 12/05/19 09:21:12.791 [88.191.115.4:53320 1 YHP] HTTP_REFERER: https://www.docteur-fitness.com/admin007/index.php 12/05/19 09:21:12.791 [88.191.115.4:53320 1 YHP] User Agent: Mozilla/5.0 (Windows NT 10.0 Win64 x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36 12/05/19 09:21:12.791 [88.191.115.4:53320 1 YHP] Accept: application/json, text/javascript, / q=0.01 12/05/19 09:21:12.791 [88.191.115.4:53320 1 YHP] Accept Encoding: gzip,br 12/05/19 09:21:12.791 [88.191.115.4:53320 1 YHP] Cookie _lscache_vary: logged-in:1 role:99 12/05/19 09:21:12.791 [88.191.115.4:53320 1 YHP] X-LSCACHE: false 12/05/19 09:21:12.942 [88.191.115.4:53318 1 LTS] Media init 12/05/19 09:21:12.942 [88.191.115.4:53318 1 LTS] CDN init 12/05/19 09:21:12.942 [88.191.115.4:53318 1 LTS] [Router] CDN bypassed: ajax call from admin 12/05/19 09:21:12.942 [88.191.115.4:53318 1 LTS] Task init 12/05/19 09:21:12.943 [88.191.115.4:53318 1 LTS] [Router] LSCWP_CTRL bypassed empty 12/05/19 09:21:12.949 [88.191.115.4:53320 1 YHP] Media init 12/05/19 09:21:12.949 [88.191.115.4:53320 1 YHP] CDN init 12/05/19 09:21:12.949 [88.191.115.4:53320 1 YHP] [Router] CDN bypassed: ajax call from admin 12/05/19 09:21:12.949 [88.191.115.4:53320 1 YHP] Task init 12/05/19 09:21:12.949 [88.191.115.4:53320 1 YHP] [Router] LSCWP_CTRL bypassed empty 12/05/19 09:21:12.982 [88.191.115.4:53318 1 LTS] [Ctrl] X Cache_control -> no Cache ( Admin page ) => LSC_Control::set_nocache()@317 => LSC_Admin->admin_init()@134 => WP_Hook->apply_filters()@288 12/05/19 09:21:12.982 [88.191.115.4:53320 1 YHP] [Ctrl] X Cache_control -> no Cache ( Admin page ) => LSC_Control::set_nocache()@317 => LSC_Admin->admin_init()@134 => WP_Hook->apply_filters()@288 12/05/19 09:21:12.986 [88.191.115.4:53320 1 YHP] [Core] CHK html bypass: miss footer const 12/05/19 09:21:12.987 [88.191.115.4:53320 1 YHP] [Ctrl] not cacheable before ctrl finalize 12/05/19 09:21:12.987 [88.191.115.4:53320 1 YHP] [Router] get_uid: 1 => LSC_Router::get_uid()@215 => LSC_Vary->finalize_default_vary()@359 => LSC_Vary->_update_default_vary()@318 => LSC_Vary->_finalize()@510 12/05/19 09:21:12.987 [88.191.115.4:53320 1 YHP] [Router] get_role: administrator 12/05/19 09:21:12.987 [88.191.115.4:53320 1 YHP] [Cfg] role in vary_group [group] 99 12/05/19 09:21:12.987 [88.191.115.4:53320 1 YHP] [Vary] show_admin_bar_front: false 12/05/19 09:21:12.987 [88.191.115.4:53320 1 YHP] [Vary] no custimzed vary 12/05/19 09:21:12.987 [88.191.115.4:53320 1 YHP] [Core] Silence Comment due to REST/AJAX 12/05/19 09:21:12.987 [88.191.115.4:53320 1 YHP] X-LiteSpeed-Cache-Control: no-cache 12/05/19 09:21:12.987 [88.191.115.4:53320 1 YHP] [Core] CHK html bypass: miss footer const 12/05/19 09:21:12.987 [88.191.115.4:53320 1 YHP] [Media] bypass: Not frontend HTML type 12/05/19 09:21:12.987 [88.191.115.4:53320 1 YHP] GUI bypassed by no counter 12/05/19 09:21:12.987 [88.191.115.4:53320 1 YHP] [Optm] bypass: Not frontend HTML type 12/05/19 09:21:12.987 [88.191.115.4:53320 1 YHP] CDN bypass 12/05/19 09:21:12.987 [88.191.115.4:53320 1 YHP] End responseExpand It depends on your hosting, please contact your hosting provider for this information.

According to them, there is no mistake on their side. @stanleylitespeed Here my log files : https://gofile.io/?c=VRWvXM thanks you.. After checking the log file, I cannot confirm the 400 error comes from our plugin. Could you try to turn [ON] LiteSpeed Cache > Setting > Debug > Disable All Features and keep working on wp-admin to see does the 400 error occurred. Also, please find the steps on how to reproduce the error for us to debug easier. Hi, Do you still need help with this? Im going to mark this topic ?Resolved? for now, but will re-open it if we hear from you again. Thanks!
