Cannot Upload Media & Warning: Cannot modify header information (2 posts)

    I would be very grateful to anyone who can help me with this issue:

    Problem:

    1 - Cannot upload media - receive following message: "The uploaded file could not be moved to C:\Inetpub\wwwroot/wp-content/uploads."

    2 - Cannot edit theme's files - receive following message: "Warning: Cannot modify header information - headers already sent by (output started at C:\Inetpub\wwwroot\wp-admin\theme-editor.php:84) in C:\Inetpub\wwwroot\wp-admin\theme-editor.php on line 99"

    Steps Taken and Failed To Resolve:

    1 - make sure all file permissions are set to 777 and they were
    2 - add a new folder to server for uploads - changed WP settings to upload to the new folder but received same error message
    3 - check for whitespace in theme-editor.php - there was no errors there
    4 - took the theme from the server, put it into a zip folder, uploaded it to a different server - and it worked fine.

    Other Notes:

    I am working with a client who has someone that runs their server-side of things. It's not my field so I don't know much about it, but he made a change to something on the server last night and since then I have gotten this error. He is very hard to work with and is saying this is an error in my php coding when I strongly believe it is not, based on my research and the fact the same files work fine on my server.

    I need a strong answer to fix this and let my client know the status. As it stands now - the website cannot have any new media added to it which is a huge issue for them of course.

    Thank you in advance.

    1. Remove the uploads folder that you added and then try changing the permissions on the wp-content directory to 766. If you still have problems, try 767, 775 or 777. Once your uploads are working, change the permissions on wp-content back to 755 again and check that everything still works OK.

    If that fails, you may need to have a word with your hosts.

    2. Solving "headers already sent" warnings

    The issue may be within your style.css or any one of your theme's .php files. Temporarily switching to the Twenty Ten theme would confirm this.

    You could also try re-uploading the wp-admin and wp-includes folders from a fresh download of WordPress.
