Image editing not working, preview not showing up

    Hallo all,

    I have WordPress 4.4.1. After uploading a Picture and clicking on edit only a broken image link is showing up where the picture to edit should be. Also cropping, rotating etc doesn’t work.

    I found that this problem already occured many times and tried all solutions, none helped:

    – different browser and deleting cache
    – changing theme to 2014 and deaktivating all plugins
    – javascript doesn’t show any errors
    – letting WP reinstall itself
    – checking functions.php (solution for an old WP)
    – folder rights are 755 ( 777 also not working)
    – GD and imagick are both enabled (most common solution, didn’t work ;( )
    – adding define(‘script_debug’ true) to wp-config.php

    Now google doesn’t deliver any new solutions.
    If you have any good suggestions please let me know!

    Thanks alot ??

    Here is the Ajax request of the backend, maybe somebody can use it:

    Nobody has any suggestions?
    Also doesn’t work with a clean install of 4.4.1 ??

    What other settings can I change on the server?
    It runs a new Debian with Froxlor.

    I noticed that when I download the picture from the ajax request, open it with notepad++ and save it again with ANSI encoding the picture is working. So somehow a UTF-8 order mark is getting there. Any suggestions where this comes from?

    Finally ??

    Here is the solution:

    Somehow a BOM was in some file… so remove all BOM in any files and make sure youre standard encoding is utf-8

    you can use this code to recursively remove all BOM in a folder

    find . -type f -exec sed -i -e ‘1s/^\xEF\xBB\xBF//’ {} \;
