Define FeedSync folder permissions ​FEEDSYNC_FOLDER_PERMISSIONS

On some servers such as WP Engine hosting the folder permissions need to be 0775 because the FTP users in their system belong to the group rather than all file access mapping back to the owner.

So while FeedSync's default permissions are 0755 this setting can be overridden using a constant defined in the config.php file.

Add the following to your config.php

define('FEEDSYNC_FOLDER_PERMISSIONS', 0775 );

So you can add the constant to the config.php and update FeedSync and maintain the 0775 permissions that WP Engine or your server requires.

After uploading FeedSync to your WP Engine Hosting run a Reset File Permissions from your WP Engine control panel under Utilities.

Cache Exclusion

With WP Engine hosting there is cache applied to the server to keep everything snappy. This will need to be disabled by the WP Engine Support team. Ask them to apply a cache exclusion the the /feedsync/ directory. Use the Live Chat and type in 'support' to get connected to a support person who can help you out.
