Missing Header

  • Same here.

    Do you mean it did not activate at all?
    Or when you try to preview/publish markdown formatted content?

    What is your WordPress version?

    I just did not look if it works after seeing the message. WP 3.8.1 on a test blog – no other plugin and default theme.

    Tested using the same configurations (WP 3.8.1, no other plugin, default theme), everything is fine!

    Where does the message appear? I might have missed it!

    Same issue. See this post for help to fix it: https://mysillypointofview.richardferaro.com/2010/05/27/fix-the-plugin-does-not-have-a-valid-header-error/

    Fixed!

    Problem:
    Installing Jetpack Markdown using ‘Widgets -> Add New -> Upload’, and trying to activate it right from the “Plugin installed successfully” page causes a missing/invalid header error.
    Installing Jetpack Markdown using any method does not cause any errors.
    Activating Jetpack Markdown from the Plugins admin page does not cause any errors.

    Cause:
    WordPress is reading the headers of jetpack-markdown/markdown/easy-markdown.php instead of (or before) jetpack-markdown/markdown.php.

    Solution:
    Make the header section in easy-markdown.php invalid to WordPress.

    Notes:
    New downloads will have this issue fixed. I didn’t increment the version number to keep the convention (same version number as the original Jetpack).

    Thanks you everyone (and Gunnar Hellekson)
