# Customizer admin-ajax.php 404

 * When attempting to save changes in the customizer(/wp-admin/customize.php) I’m
   getting a 404 error from admin-ajax.php. I get a 200 from admin-ajax.php when
   modifying widgets (/wp-admin/widgets.php).
 * Any ideas what’s different in the customizer context that would result in a different
   response behavior?
 * In searching, people have asked to verify
    1: that the file exists: yes it does
   2: permissions: 640, which is correct for my environment. I changed to 777 to
   test but it made no difference.
 * Thanks for any ideas

 * Hi,
 * Could you try to disable all the plugins and switch to a default WordPress theme
   to see if it works? 🙂

 * I guess I should have mentioned I did that before posting. Yes, problem persists
   regardless of theme and with no plugins active.

 * Sorry for the late reply. Didn’t notice an email. You should contact your hosting
   provider as it appears to be an issue with your mod_security.
 * Let me know how it goes. 🙂
