 * Hi guys.
 * I seem to have stumbled upon a strange issue that I can’t wrap my head around.
   WordPress will throw a 404 error whenever I include a < character inside the 
   post content (like an <h2> tag). On both posts and pages.
 * I have tried:
 * – disabling all plugins
    – changing the theme – replacing all wordpress files–
   switching php versions in cPanel
 * The .htaccess file is default.
    //edit: everything is updated
 * Any ideas?

 * It appears when I click on the publish/update button. “Error 404 – page not found”
   on wp-admin/post.php (file is there of course)
 * The post can include only the single < character (and nothing else) and it will
   throw the error.

 * No, the post or change does not get published. Even if i click on “save draft”
   it goes to the 404 error.

 * Do you have access to your site’s error logs? You might get more informative 
   errors in there

 * I have error_log access (via cpanel), but it looks like it’s empty. I turned 
   on the debug.log logging and all it logs is a deprecated issue regarding US_Widget_Contact.
 * Notice: The called constructor method for WP_Widget in US_Widget_Contact is deprecated
   since version 4.3.0! Use __construct()
 * Checked for updates, still on latest everything.

 * Change “<” to “<” and see if it works.

 * [@rtwk](https://wordpress.org/support/users/rtwk/) I’m guessing your code got
   cleaned up in some way, seems to be same character (the “less than” character
   in HTML)
