Still doesn’t work after the workaround
1. Comes packaged inside a subdirectory called ”list-recent-sites.php”, which causes it not to show up under plugins after installing. Can be worked around by moving the files from within ”list-recent-sites.php” up in the directory tree (into list-recent-sites/).
2. Still doesn’t work after the aforementioned workaround and activating: the function displays nothing.
