  • i just reinstalled a clean version of wordpress. when i want to customize the theme by adding a menu name “social links menu” with custom links to the different sites i cannot save.
    I always get the following error:
    POST 404 (Not Found)

    i tried disabling all plugins and rolling back 1 modification i did to the functions.php file that i read in the jetpack documentation for using only login function.

    Other than that, i cannot update the theme.

    tried adding to .htaccess
    <IfModule mod_security.c>
    SecFilterEngine Off
    SecFilterScanPOST Off

    but did nothing.

    Also as a note, the file does exist.

  • You must have fixed it, since a request to the URL it is now returning HTTP 200, so the file exists. If you paste the URL in the browser you should see a zero.

    Did you solve your original issue?

    retried with a clean install and no imported posts or configurations and still happens.
    tried removing cloudflare dns and still nothing.

    reset .htaccess to default from instalation and checked vs the wordpress codex

    # BEGIN WordPress
    <IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteRule ^index\.php$ – [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.php [L]

    # END WordPress

    still error is maintained.

    I am experiencing the very same issue with the HashOne theme from HashThemes. Cannot save any appearance customizations.

    Actually – just discovered I CAN delete something from the primary menu, but cannot add anything to it.



    Ever find a solution to this?

    Changed hosting




    I have also a wordpress admin-ajax.php problem: First my WordPress admin-ajax.php returns 0 and now it’s a clean sheet.

    I tried the answers online but still no reaction. Can someone help me please 🙂




    This should be related to your host’s web application firewall. Try contacting them.

    For me, that was the solution. Hope it helps to you too.
