This theme failed to load properly and was paused within the admin backend.

Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies with an automated email. This typically happens when installed active themes or other components are updated.

A customer ran into this with Astra theme. Their website would just display a maintenance error and costed their business few hours. Automated alert from WordPress didn’t offer any assistance. They reached out to us and we had to use WordPress’s recovery mode and had to updated all installed plugins, verified that other inactive themes are functional and concluded the issue wasn’t related to hosting provider.

We just needed to uninstall and reinstall the active theme Astra to get the site back functional and customer was back on business.
