 * Hi [@roundaboutweb](https://wordpress.org/support/users/roundaboutweb/),
 * You can see the plugin directory paths in _WooCommerce > PDF Invoices > Advanced
   > Status > Directory Permissions_ (located at the bottom). There, you can also
   check the current permissions for each directory.
 * Please note that you can change the file system method, if you need it, in _WooCommerce
   > PDF Invoices > Advanced > Settings > File System Method_:

 * I don’t understand the error message. According to the permissions overview, 
   all directories are writable, yet the error message still appears.

 * Thanks for the screenshot, [@roundaboutweb](https://wordpress.org/support/users/roundaboutweb/):
 * It looks like your server does not have the PHP FTP extension enabled.
 * Could you please enable the PHP FTP extension for your website? You can usually
   do this in your hosting control panel under PHP settings or “Select PHP Extensions”.
 * If you’re not sure how to do this, please contact your hosting provider and ask
   them to enable the PHP FTP extension (ext-ftp or ftpext) for your account.
 * Once it’s enabled, please try opening a generated PDF invoice again to check 
   that everything works correctly.
