One of our devs left last week and I inherited some tasks for one of his projects. I've never really worked with WordPress and I am not overly familiar with PHP (I am an app dev), so I am completely lost here. Basically, our Facebook feed (which is using the Facebook Feed Grabber plugin) will not display. When I went into the admin panel in our testing environment, it said the following:

enter image description here

I am assuming this is the issue. We cannot cache any data therefore no data can be displayed. The path is relative to the old dev's work env and I cannot get it to change. After some digging, I found a line in the facebook.php class that seems to be the setting for that option.

'cache_folder' => WP_CONTENT_DIR. '/uploads/cache/',

I also tried changing that to content_url( 'uploads/cache' ) as well and ended up with the same result. Could anyone point me in the right direction?

Change your permission to 664 to the uploads and its cache directory inside. Learn more here.
