    I use MAMP to create a website locally for test, when install this plugin, it show this message and nothing else. I have to go to the folder to delete it. Then everything back to normal. I see your plugin work fine recently. Is it because of MAMP ?

    @hungpham: no, sir. There are a lot of free space in my Mac

    Plugin Author Tran Ngoc Tuan Anh


    That’s strange. Can you try deactivating all plugins and re-activate Meta Box again?

    And can you turn on debug mode to see if there’s any error message. The way to enable debug mode is here:

    So I reset WP and it’s work.
    Than I go to state where it’s crash and deactive all plugin. It’s work again. Then I turn on debug mode and active all plugin. Here is what screen show:

    Plugin Author Tran Ngoc Tuan Anh


    Oh, that’s it! The last line says the error is in the plugin called levelup-core. Looks like the author is embeding the Meta Box plugin, but not the right way (or include the very old version).

    Can you contact the plugin author and ask him to check this out?

    This is the documentation on how to integrate Meta Box into other plugins or themes:

    Ok, Thanks a lot guys.
