Hello,
I’m very sorry to hear about the issues deploying your staging site. If you’re using BoldGrid’s Staging plugin, we no longer recommend using this plugin, and recommend using BoldGrid Cloud WordPress to create staging sites separate and safe from having any effect on your live site.
If you’re using BoldGrid Total Upkeep, I recommend restoring your most recent backup to recover your site. Your web host may also keep backups so that your can restore your site.
