WP sites not loading after updates
May, 2018.
This turned out to be a problem with the php allocation.
From Liquid Web tech support:
During our conversation, we found that your site was not loading properly due to the memory_limit being lower than what was needed to load the site. I raised it from 64M to 128M, which brought it back into working order.
I did this by adding the following line to
public_html/.user.ini:
memory_limit=128M
