# Javascript console always shows 404 error for /null

 * Every WordPress site I am building shows 404 (Not Found) error in the Javascript
   console for a file called null. I have confirmed that this happening on a clean
   install of WP 5.9.3 without any plugins, settings changes, or database edits.
   This error looks like this for every page/post on the site:
 * `GET http://wptest.local/2022/04/18/hello-world/null 404 (Not Found) wptest.local/:
   344`
 * The referenced line number (in this case 344) is simply the last blank line of
   that page’s rendered HTML.
 * Saving my permalinks in tools gets rid of the error for _anonymous users_ but
   the error remains if I am logged in to my site despite this.
 * What’s going on, is there any fix for this?

 * The query WP makes cannot find any resource called “null”, hence it returns a
   404. Why does /null appear in permalinks or why is it requested? It’s abnormal
   in a typical WP installation.
 * If it is supposed to do something specific, similar to /feed, it needs an added
   rewrite endpoint that tells WP how to handle such a request. If such an endpoint
   has been added for that effect, flush the rewrite rules to make it active by 
   visiting the permalinks settings screen (no need to save anything, just load 
   the screen).

 * As I mentioned, this is a 100% clean install of WordPress (WAMP Win10, but I 
   also see the exact same 404 error on Pantheon, MediaTemple, Bluehost installs).
 * Something in the core install is looking for /null on every page request. I have
   no idea what it is or if there’s a basic setting I’m missing.. If you want a 
   see it in action, open the Web Dev console on these sites (all on different hosts):

 * I have re-saved permalinks on all these sites and the error persists, even for
   anonymous users.

 * I’m beginning to suspect this might be something in my Chrome browser setup. 
   I am seeing the error on this forum Web site too! But not in Edge. I’m investigating
   further…

 * I found found the problem! It was the <i>CrxMouse Chrome™ Gestures</i> Chrome
   extension. I will report this to the extension author.
