add_theme_support(‘post-thumbnails’) > blank pages render over submit post

    Hi,
    I’m following several courses right now, in two cases, when I, building a new theme, enable the option to upload a feature image by add_theme_support(‘post-thumbnails);, the option doesn’t work properly and when I update the page the next screen is a blank page.

    I click the browser back button to continue and can see the page was created/updated but without an image.

    No image show up in the feature-image al all in any moment.

    I work in Mac OsX 10.11.6 with MAMP 4.1.1, test in Chrome 56.

    Thanks

    Are you sure you have the right quotes? The code you posted above will surely throw up an error. Has a missing single quote after thumbnails.

    add_theme_support( 'post-thumbnails' );

    I wrote it bad in the post text but it’s fine in the code.

    add_theme_support('post-thumbnails');

    Thanks

    add_theme_support('post-thumbnails');, NOT GUILTY.

    I comment it out but the blank pages still around (at this url: http://localhost/hotelspa/wp-admin/post.php)

    BUT, things started to get messy when I add this function. Quite weird!

    Got it!

    I found this comment in a Treehouse forum:

    So weird.
    In case anybody else is having this “white page of death” issue, the resolution for me was simply to delete any empty lines after the closing ?> in functions.php.
    Can any of the mods explain why thee empty lines would cause this error?@

    I tried it and works!

    So, delete any empty lines after the closing ?> in functions.php. 🙂

    Even more; I can see there’s no need to ?> at all!

    No necessity to close or “block” a file that is a single PHP as a whole.

    Lost some elegance, but avoid for sure the weird response to empty lines.
