HTTP error when uploading media over 100k

  • Since upgrading to WordPress 3.2, I get HTTP errors when uploading images over 100k in size. I have scoured the forums and implemented every recommendation made, but to no avail.

    • The image I am attempting to upload is a JPG under 300k and 580×270 pixels in size – hardly a huge image.
    • I am running PHP 5 on a MediaTemple VPS running Plesk. I also have the latest version of Flash installed on my computer.
    • I have the Image Upload HTTP Error Fix plugin installed, which adds code to .htaccess that disables mod_security.
    • I have increased my post_max_size to 8M and upload_max_filesize to 8M in php.ini.
    • The upload folder is writeable and I am able to upload images under 100k.
    • I have replaced my entire WordPress installation.
    • I have attempted disabling all plugins.
    • I am not using a custom upload location.
    • My error_reporting level is set to &E_ALL but if I tail -f my error_log no error appears when the upload fails.

    Anyone have a clue?

  • HTTP errors are normally due to mod_security and need to be addressed at the host/server level. See https://www.chewie.co.uk/general/wordpress-image-upload-http-error/

    Thank you, but as noted above, I have the Image Upload HTTP Error Fix plugin installed, which adds code to .htaccess that disables mod_security. I’ve tried four different versions of that code manually inserted into .htaccess as well.

    Another note: The error does not occur with the HTML uploader.

    I have the Image Upload HTTP Error Fix plugin installed, which adds code to .htaccess that disables mod_security.

    That does not work with all hosts. Have you asked your hosts about this?.

    yes. phpinfo is showing mod_security as successfully disabled.

    Since it works with the normal HTTP uploader and you’ve ruled out mod_security and PHP’s post_max_size and upload_max_filesize settings, maybe it’s a flash issue. (I don’t know why it would throw an HTTP error though; my knowledge of flash voodoo is limited)

    Does it give you the same problem in other browsers/operating systems/computers?
