Hi have an error 🙂 I setup it on localhost. I turn off all plugin and install metabox to check. 🙂
Fatal error: Cannot declare class MB_Updater, because the name is already in use in C:\xampp\htdocs\Check\wp-content\plugins\meta-box-updater\class-mb-updater.php on line 11
Which theme are you using? That's strange. If you deactivate all plugins except Meta Box, the file C:\xampp\htdocs\Check\wp-content\plugins\meta-box-updater\class-mb-updater.php will not be loaded.
