About 45 minutes ago (8:00 AM Eastern) the site would not load and be stuck on the loading page (colored dots).
This is due to a plugin for the math equations, I do not know which one is causing the problem so disabled both.
For examples see: Post for testing installed component themes and plugins AKA test page
In the future when stuck at the loading page for more than a minute use safe mode,
When the plugin is fixed I will reenable them.
This is now working as expected, details can be read at this Discourse topic.
