Support » Networking WordPress » File type does not meet security guidelines

  • Hi there,

    i activated the multisite feature in my blog and the most things are working correctly. Except the plugins and the file upload.

    In this topic i just want to find a solution for the upload problem. if i try to upload an image i get the following error:

    Warning: Invalid argument supplied for foreach() in …/wp-includes/functions.php on line 2365. Dismiss “image.png” has failed to upload due to an error. File type does not meet security guidelines. Try another.

    I have allowed to uplaod png files and there is enough space. Someone have an idea what could be wrong?

    Thanks in advance!

  • Check for caps or not.

    Go to Super Admin -> Options, “Allowed file types”.

    paste in here what you put in there.
    Also give a link to your site. Yes, it really does help.

    “Allowed file types”: jpg jpeg png gif pdf

    And the links to my site.
    Main Blog: (In this Blog everythings works fine)
    Blog “2”: (Problem like described above)

    Notice: To setup WP Multisite with Multiple Domains i used the following way:

    Get to domain mapping plugin, it’s much easier.

    The author of that post was unaware there was a plugin that did all the work for you. (and there’s a couple extra bits)

    It’s possible if you changed the site_id table to 2, you’ve basically made a second *network* not a second site. The tables use old WPMU terms, it’s a little confusing if you’re not used to it. The second network will also have the ability to have child blogs.

    Go to Double check the allowed files there. My guess is png isn’t on this one.

    @andrea Thanks for your help!

    Unfortunately i got the error “You do not have permission to access this page.” But i am sure that i’m logged as admin.

    But your comment redarding the second network is very interesting. i still have some more problems with the news site/network. So i think it could be better if i revoke all edits and try the plugin you recommend.

    Do you think that’s the better way, too?

    Yes, I do.

    OK, now i deleted the created blog and all tables in the database and added a new one. With the named plugin above everything works fine!


    I am having a similar problem trying to upload kml and gpx (mapping) files. I am also new to wordpress… how to you “Go to Super Admin -> Options, “Allowed file types””?
    I am logged in as the original “admin” for the site and don’t see any such setting.
    using wp 2.9.2

    You only get the Super Admin menu if you are running a network of sites in 3.0.

    You get a Site Admin menu if you’re running WPMU 2.9.2.

    If you have a single WP install before 3.0, you don’t get this area.

    Hello, I’m also having this problem, using wordpress 3.0 without MU feature activated. I tried to upload a 2 mb 7z file and I keep receiving this message though I have made sure to increase file size limit in php.ini (I’m using vps with kloxo installed)

    Could anyone help me?
