Hi Leah - Thanks for reporting this so quickly. The problem stems from the release, about an hour ago, in which the list-category-posts plugin was updated to the latest version. The plugin developer renamed the main plugin file from list_cat_posts.php to list-category-posts.php. WordPress identifies active plugins using this filename, so when the filename was changed, WP assumed that the plugin was deactivated.

I wrote and ran a script that corrected the problem across the network. (https://gist.github.com/boonebgorges/25ba440369b875372656, for future reference.)

The script doesn't work on sites where the plugin has already been deactivated. As you found out, WordPress will deactivate a "lost" plugin when you visit plugins.php. So I've manually reactivated the plugin on the murphyinstituteblog.org website. This probably only affected you, since the release just went live a few minutes ago (and, as noted, you had to visit wp-admin/plugins.php to make the deactivation stick).

Let me know if you continue to have problems.
