    Hello Metabox Support Team,
    I am encountering a critical error on my website that is causing it to crash constantly. I've been experiencing this issue despite trying various combinations of WordPress and PHP versions for the past couple of weeks. It's becoming frustrating and very urgent now.
    Here's a breakdown of my setup:
    • WordPress Versions Tested: 6.8.3, 6.9
    • PHP Versions Tested: 7.4, 8.0, 8.1, 8.2, 8.3, 8.4
    • Metabox IO Extensions Enabled: Relationships, MB Post Types and Custom Fields, and MB Builder
    • Enabled Metabox Plugins: Metabox Builder, Relationships, and Metabox standalone plugins
    The error message I'm seeing is: "Reference error: There has been a critical error on this website. Please check your site admin email inbox for instructions. If you continue to have problems, please try the support forums."
    I've already checked my site admin email inbox for instructions, but I haven't found anything that resolves the issue.
    Could you please assist me in diagnosing and resolving this critical error? I rely on Metabox for my custom post types and fields, and the constant crashing is significantly impacting my site's functionality.
    Thank you for your time and assistance.
    Sincerely,
    Irfan
