Hi there
When ever open my admin panel it gives the message install Meta Box plugin. when Install and activate the plugin it gives There has been a critical error on your website. Please check your site admin email inbox for instructions.

and if I delete this meta box and site’s front end give the following error.
There has been a critical error on your website.
that plugin broke when it was last updated – it is not related to GeneratePress.
I believe the plugin author is working on a fix. But you may want to consider an alternative plugin.
