Support » Plugins » [Plugin: Flexible Upload] Not compatible with WordPress 2.6?

  • Dalton Rooney


    When trying to upload an image in 2.6 with Flexible Upload enabled, I get the following error:

    call_user_func_array() []: First argument is expected to be a valid callback, 'media_admin_css' was given in /****/****/****/****/weblog/wp-includes/plugin.php on line 311

    Is anyone else having this problem? Thanks.

    same problem here..






    Yep, me too.



    Same problem but the he plugin seems to work if the images are stored in wp-content/uploads .
    I’m afraid the conceptor is in hollydays so if somebody find a solution…



    There is a good lesson here – if you have plug-ins that you want to keep, don’t upgrade WordPress until those plug-ins have also been upgraded.

    There is a note on the Flexible Upload homepage, in the forum, from the developer. FU is not compatible with WP 2.6. He says he’ll work on it.

    Fortunately this plugin isn’t mission critical for me. In fact, this might be the time that I finally get used to WordPress’ built in image management tool.



    same problem here.



    I have the same problem. Thankfully i tested it out on another blog first. Actually with the upgraded wordpress I’m liking the new adding images a lot better. You can edit immediately and even adjst the sizes, plus lightbox works fine for me.

    My only issue is that I STILL cannot do multiple images with wordpress. The keep saying there is a http error which crunching.

    But I can still use Flexible upload… just that the error coding is a bit of an eye sore.



    This solution isn’t pretty, but it got rid of the error message and will probably work until a real fix is found.

    Comment out line 65 of wp-content/plugins/flexible-upload/flexible-uploadwp25.php

    add_action('admin_head_fup_media_upload_form', 'media_admin_css');



    +1 would be great to have an official fix



    Is there any other plugin which does this? All I want is the ability to resize the image.


    +1 wait an official fix

    A WP 2.6 fixed version can be obtained here: (scroll down for the download – if there is enough interrest I’ll translate the post to english also)

    A translation of that post would be great.

    Please do translate.That would be so great.
