tl;dr: some posts look funny for reasons beyond my control. Please be patient with visual glitches until I’m able to fix it.
willangley.org used the Genesis Blocks plugin for some posts. Jetpack Scan alerted me that this plugin had a security vulnerability early this morning.
Because deactivating WordPress plugins does not reliably protect against plugin vulnerabilities, I uninstalled it before leaving for work.
The plugin has been patched, but I cannot reinstall it; it’s currently closed pending a full review.
