"The Link You Followed Has Expired"

‘The link you followed has expired’ error usually occurs when you are trying to upload a WordPress theme or a plugin that is bigger than the file size limits"
check current max size at Media > Add New Media File. (in my case 8MB)

#  Facebook Page Photo Gallery plugin not showing thumbnails 
From https://wordpress.org/support/topic/thumbnails-didnt-load-any-more: Since WordPress 4.0 the thumbnails didn't load any more. So began searching for the loading of thumbnails in your code and tried commented out line 7 and 8 of single-album.php and line 3 and 4 of single-album-ajax.php and added
  $picture = $photo->picture;

#  Set file permissions 
https://wordpress.org/support/topic/auto-upgradeupdate-on-mac-os-x
On Mac OS X (Leopard), the Apache HTTP Server runs under the user account, _www which belongs to the group _www. To allow WordPress to configure wp-config.php during installation, update files during upgrades, and update the .htaccess file for pretty permalinks, give the server write permission on the files.

One way to do this is to change the owner of the wordpress directory and its contents to _www. Keep the group as staff, a group to which your user account belongs and give write permissions to the group.

  $ cd /<wherever>/Sites/<thesite>
  $ sudo chown -R _www wordpress
  $ sudo chmod -R g+w wordpress
This way, the WordPress directories have a permission level of 775 and files have a permission level of 664. No file nor directory is world-writeable.
