 * Hello,
 * I am trying to get WordPress working on my Raspberry Pi. I just installed the
   latest version with Apache2. It seems to work, but only if I have the Permalink
   settings at “Simple.” Anything else gives me the “Updating failed. Error message:
   The response is not a valid JSON response.” Or a web page “Not Found” if I try
   to preview my change. Thanks for you help,

   to see the link]_

 * Hi [@ranastron](https://wordpress.org/support/users/ranastron/),
 * Maybe it seems a permission error to your files due to which wordpress is not
   able to create/update .htaccess file for updating the rewrite rules.
 * Please make sure your file permissions are as follows:
    Directories: 775 Files:
   664 Here is the commad for same: `sudo chmod -R 775 /folder` `sudo chmod -R 664/
   folder/*`
 * Also the group or owner of the files should be ‘www-data’.
    `sudo chown -R www-
   data:username /folder`
 * Once these permissions are set, try changing the permalink structure again.
 * Please let us know your response on this.

 * That was my thought as well, so I had made sure the group was www-data, and the
   permissions were set. I even double checked that Apache2 was running as www-data.
   No change in the behaviour.

 * a knowledgeable friend advised that I turn on the mod_rewrite module in Apache2.
   That seemed to fix the problem. I wonder why it wasn’t turned on by default?
