On the Plugins page in wp-admin I see this:
Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the boldgrid-backup domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later. Please see [Debugging in WordPress](https://developer.wordpress.org/advanced-administration/debug/debug-wordpress/) for more information.

I took a backup and was trying to see if it worked, but trying to delete a page caused a white screen with this:
