 * It just says error when I make change and try to save it. The message is there
   for a few seconds and then disappears.
 * Updates today to 6.4.1, but still the same error.

 * The HTTP **406 Not Acceptable** error usually means that the server **cannot 
   generate a response matching the `Accept` headers** sent by the client. While
   rare, this can happen in WordPress admin AJAX requests due to a few common reasons:
    1. **ModSecurity or another Web Application Firewall (WAF)**
       — This is the most
       frequent reason. ModSecurity might block AJAX requests it considers suspicious—
       for example, if they include a `Content-Type: application/json` header or specific
       POST parameters.
    2. **Strict `Accept` headers from the client**
       — If the JavaScript request sets
       a very specific `Accept` header (like `application/json`), and the server doesn’t
       support it or filters it, it may return 406.
    3. **Blocked request body content**
       — Some hosting providers filter or block certain
       characters or patterns in POST bodies — like SQL strings, JSON, or base64 — 
       thinking it’s malicious.
    4. **Incorrect `Content-Type` or malformed response in plugin/theme code**
       — If
       the plugin or theme manually sets headers or outputs a non-standard response,
       the server may reject it.
 * How to troubleshoot:
    1. **Temporarily disable ModSecurity or ask the hosting provider to whitelist `
       admin-ajax.php`**
       — This is often enough to resolve the issue.
    2. **Check server logs (access/error logs)**
       — They may show which rule was triggered
       and caused the 406 response.
    3. **Inspect the browser’s developer tools (Network → Headers)**
       — Look at the 
       request and response headers, especially `Accept`, `Content-Type`, and the actual
       response body.
    4. **Try making the same AJAX request without a strict `Accept` header**
       — For 
       example: `fetch(url, { headers: { Accept: '*/*' } })`
    5. **Temporarily disable security plugins like Wordfence, iThemes Security, etc.**
       —
       These plugins sometimes interfere with admin-ajax calls.
 * If the above does not help, you should ask the hosting support for help.

 * Thanks you.
 * The issue was with the hosting security triggered. The admin solved it. Thanks
   again for the quick response.
