Wordpress LScache Plugin: Error 400 after update post

Last Updated on: Wed, 15 Apr 2026 00:00:02
Hello, Num?ro de rapport : CPEXRDCZ After updating my site, I disconnect from the administration and when I go to the site I get an 400 error. I have to refresh the page to be able to display it. So I have to go to each page to refresh because if a visitor comes back he will have a 400 error. On the other hand, on all the pages which contain a form I activated ESI and I never have error 400 on it. I tried with all the plugin deactivated, its always the same problem. I tried to purge all after update, its always the same problem. I tried in private navigation after having made an update and I dont have the problem. Can someone help me for the configuration because this plugin is impressive of speed ! I want it to work on my sites without any error ! Thank you very much Greg Hi, You mean you get 400 bad request when edit/publish post/pages ? Please try clean up your browser and see how it goes. Also please try disable ESI , how does it go ? Best regards, Ruikai. Hello, Error 400 occurs with and without ESI. If I empty the browser cache I dont have a problem. If I empty the browsers cache I first go back with this browser for the first display of the page and then I go back with another device that does not have an empty cache and the pages are displayed without error. I tried to purge all the cache with plugin before returning to the site but it still makes error 400. So I have the impression that I have to first go through all the pages of the site with a browser that has an empty cache so that returning visitors dont get error 400. If they are the first to display a page after the update they have the error. If I have already loaded it before by passing over it there is no problem. And also if I go back to the site with the same browser, after 3-4 days (without making an update) I have again an 400 error. I think its the server cache that has to do a task. sorry for my bad english and thank you for this amazing plugin. Greg from france Hi, Yes, your server environment seems using LiteSpeed ADC, which is a reverse proxy to your backend , I think the issue might lays there. Please submit a ticket here, we will investigate it further. Best regards, Ok thank you, i can disable plugin for the moment ? I send you a ticket with rapport number and dologin link. Thank you Greg
