 * Hi all,
 * My main problem is that I am missing the admin-ajax.php file in the wp-admin/
   folder. I noticed it when I repeatedly was not able to upload a picture to a 
   post. So I used the “Developer tools” in the google Chrome browser to identify
   the problem and I got following message:
 * > “[http://www.ursmuehlematter.ch/wp-admin/admin-ajax.php](http://www.ursmuehlematter.ch/wp-admin/admin-ajax.php)
   > Failed to load resource: the server responded with a status of 404 (Not Found)”
 * The file is not visible using an FTP program (show hidden files activated)
    I
   tried to reinstall my theme (Pixelgrade/lens) but the same error appears. The
   problem is reproducible in firefox, edge, chrome. It did not solve even tough
   I deactivated all plugins.
 * Is there any easy way to restore that file/solve my problem.
 * Thank you for any help,
    captcoma

 * admin-ajax.php is part of WordPress, not your theme. Since you can’t tell what
   else might be missing, consider reinstalling WordPress using the “Resinstall-
   now” button in Admin page > Dashboard > Updates. If you are experiencing other
   unusual behaviour this may be a sign you’ve been hacked.
