    I have the same problem when I try to enable any plugin. I just updated to WP 2.8 with the automatic update.

    and further the forcibly deactivated plugins no longer show up in the plugin list.

    Guys, I've found an workaround. Just move plugin files to /plugin root. For example:

    /wp-content/plugins/akismet/akismet.php

    Move akismet.php to

    /wp-content/plugins/akismet.php

    Your plugins' folder will be a messy, but at least missed plugins will come back and work.

    Anyway, I'm still waiting an official solution from Automattic. WP 2.8.1, may?

    []'s!

    rghedin:

    I'll try that.

    I'm getting tons of spam since I upgraded to 2.8 on Wednesday. It's like the spam filter is not there!

    My plugins look fine within the the plugin listing in the WP8.0 Dashboard, but am getting tons fo spam since the upgrade.

    Yes... the Askimet seems to be activated, but not working well.

    I am wondering if the rules have changed. I did manually upgrade to the new version of Askimet as was requested of me. Is that not working too?

    What a mess!

    Thanks in advance.

    I find another way to solve this problem.

    Just wanted to share real quick that this issue also is present in SVN managed installs. A quick switch from tags/2.8/ to /trunk/ does NOT resolve this issue either, just in case anyone in a similar setup was thinking of trying.

    I still have the problem. I have tried both suggestions and I still get the same error.

    No official solution yet? I really can't get along with this trouble. Some plugins, which have many files into folders, doesn't work with tips said above. I just can't use some plugins in my blog anymore :-( .

    Hope Automattic give us at least an explanation about what happened.

    Having the same issue here.

    I was able to activate it by moving it manually into plugins. When you use the installer it has a file and within it there were multiple folders ie. screenshot and the one I needed. Moved it out of that folder into plugins and it activates.

    I've already solved this - for any plugins. I wrote an article here.

    WP 2.8.3 and plugins

    As someone mentioned, some plugins will only install manually like we used to do before the automatic install feature.

    Unzip the plugin folder and upload it via FTP into the wp-content/plugins/ folder.

    Make sure you ONLY upload the plugin folder:

    wp-content/plugins/askimet = good
    wp-content/plugins/askimet/askimet = not good

    That's why the header can't be found, it doesn't seem to discard the "shell" folder.

    Hope this helps!

    Hi, I am sorry, but I am new to WP, how do you "move these files out of the plugins folder and into the root folder" ? I have no WP folders on my Mac, and I can't find any directory under http://www.globalmacroblog.com/wp-admin/

    Any help would be great as I am unable to install any plugins at all - I get the same message. Do you know if this will ever get fixed, it seems people have had problems for months now.

    wtf! wordpress... this is really bad. can we get some responses from wordpress dev team? the plugins are broken, whether manually installed or not.

    If you are running the latest version of WordPress and plug-ins that are compatible you will not have this issue. If the problem still persists then you need to deactivate all your plug-ins. Reactivate them one at a time until you figure out which are the culprits and inform the plug-in developer.

    If you are creating a new plugin make sure that you have this in your main plugin file.

    <?php
    /*
    Plugin Name: Name Of The Plugin
    Plugin URI: http://URI_Of_Page_Describing_Plugin_and_Updates
    Description: A brief description of the Plugin.
    Version: The Plugin's Version Number, e.g.: 1.0
    Author: Name Of The Plugin Author
    Author URI: http://URI_Of_The_Plugin_Author
    */
    ?>

    Another easy way to fix this problem is to upload the UNZIPPED folder using the regular FTP way and then going to your plugins panel in wordpress and activate it.

    I'm using the "Magic Magnify" plugin and I kept getting the 'The plugin does not have a valid header.' message, but this method seems to work. There might be a problem in the way WP has been configured with certain plugins.

    I hope this helps.

    I also ran into this problem recently. In the end it's to do with the permissions on the plugins directory. The web server needs write access to certain files when they are uploaded. If your server is running with group write permissions, the upload script doesn't necessarily set the group write bit on the necessary files, only owner write permission.

    I've had the same problem. Drove me insane. Here's how I found a fix.

    In the "Install New Plug Ins" page, rather than UPLOAD your plug in from your desktop or download file (which is where you'll probably be loading the file from) SIDE STEP this step by using the SEARCH function to find the plug in on the WordPress.org site, then press "SEARCH PLUG INS".

    If the plugin you're looking for is on the main WordPress.org site, you ought to be able to find the plug in you're looking for pretty easily, then, once you find the plug in, way over on the right hand side of the page there's a wee link that says "Install".

    Hit that button and bingo! Your plug in ought to be installed and activated all in one go. Try it and see if it works. It worked for me. How? Dunno. Frankly, I don't CARE, all I know is that this simple, simple step saved the second half of my day.
