Fixing the white screen of death

Child themes are still the correct way to override a theme you do not control.

After juggling a dozen WP sites for clients, I have opinions on pretty much everything WordPress.

My rule of thumb: if a plugin has not been updated in a year, it is a liability.

wp-cron only fires on page views, so low-traffic sites should switch to system cron.

Any tips, experiences or strong opinions welcome.
