Wordpress LScache Plugin: litespeed causing ERR_HTTP2_PROTOCOL_ERROR
Last Updated on: Wed, 15 Apr 2026 00:00:02 The site keeps showing an ERR_HTTP2_PROTOCOL_ERROR whenever a new post is added to the site. However, this error shows up only if the user is not logged in to the WordPress dashboard. And also, if we disable the plugin, this error does not occur when we add a new post in the site. Can you please help. The litespeed report number that I have generated is JDPOTMOW Hi, Could you please state the steps to reproduce ? publish a new post will trigger it ? Best regards, The error happens right after publishing a new post. people will start getting the error message (ERR_HTTP2_PROTOCOL_ERROR) on their browsers and this happens on all devices. after waiting for sometimes upto 10 minutes the error will disappear the site becomes accessible. The site supports HTTP2 (We are using wordpress). But as admin logged-in I can see the frontend of the site when others are getting the error. This does not happen when cache is disabled. Hello. I have exactly the same problem. Version 2.9.9.2 does not display this warning, but version 3 provides this warning. I saw several other users mention this. Why dont you take care of it? thank you Hi, Could you please try disable all other plugins, and only leaves LSCWP on , and see if it still happens ? Best regards, Hi, Im going to mark this topic Resolved, due to lack of activity. If you still need help, please tell us: what happens when you disable all other plugins and leave LSCWP enabled? Do you still see the same warning? Well be happy to reopen the topic if necessary. Thanks!
