# litespeed causing ERR_HTTP2_PROTOCOL_ERROR

 * 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

 * 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 don’t you take care of it? thank you

 * Hi,
 * I’m 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?
 * We’ll be happy to reopen the topic if necessary.
 * Thanks!
