Support » Fixing WordPress » Intermitent HTTP Error on Media uploads

  • Hi,

    I’m have intermitent problems on with media uploads. Appears to only be a recent thing since updated to 4.5.2. All themes etc have been updated. I’ve tried editing the .htaccess file as mentioned in other posts etc. No need to re-size images, and one moment they will upload, the next they will not.

    Any ideas?

  • Add this below code in function.php fle

    add_filter( 'wp_image_editors', 'change_graphic_lib' );
    function change_graphic_lib($array) {
    return array( 'WP_Image_Editor_GD', 'WP_Image_Editor_Imagick' );

    If above code is not work , follow below steps to remove error

    1. Decrease the image’s size. Don’t add a 2000 x 1500 image, for example. If your post content area is 700px wide, don’t add an image larger than that.

    2. Change the image’s extension from .png to .jpg, or vice versa, then upload it again.

    3. If the problem appears after installing a plugin, deactivate it and try it again. Some plugins can trigger the error.

    4. Increase your PHP memory. Add this code define(‘WP_MEMORY_LIMIT’, ’64M’) into your wp-config.php file. This setting may not work if your host does not allow you to increase the PHP memory limit, so I suggest talking to your support directly and ask them to change the limit for you. You’ll skip the hassle.

    Read this guide if you need to know how to access and edit your WordPress files.

    5. Add one of these codes in .htaccess:

    <IfModule mod_security.c>
    SecFilterEngine Off
    SecFilterScanPOST Off


    # Exclude the file upload and WP CRON scripts from authentication

    <FilesMatch "(async-upload\.php|wp-cron\.php|xmlrpc\.php)$">
    Satisfy Any
    Order allow,deny
    Allow from all
    Deny from none


    AddType x-mapp-php5 .php (at the very top of your .htaccess file)
