   activated. But the link that sais activate the plugin still sais activate (it
   should say deactivated) and the plugin is not activated.

 * I have the same problem with WP2.0. I have made sure that the plugin is correctly
   installed.
 * Yesterday I had lots of problems with this, now in the morning i found that one
   plugin had the “deactivate”-button, but i cant deactivate it in the same way “
   maddeadde” cant activate her/his plugins.

 * I had the same problem until I stumbled across this site:
    [http://blog.hypercubed.com/index.php/archives/2005/12/26/wordpress-20-fix/](http://blog.hypercubed.com/index.php/archives/2005/12/26/wordpress-20-fix/)
   I replaced the first 25 lines of code as he suggested and whamo, my plugins now
   activate. just be sure to grab that last line of code with the ending bracket}.
   I missed it the first time and it returned many more errors than what I originally
   had.

 * You can also just download this copy from the SVN which has the patch applied:

 * The fix suggested by dieterich worked for me.
 * FYI i’m using Windows Server 2003 with Plesk 7.5 for Windows.
 * But now I’m about to load the new plugins.php since I just noticed it at the 
   bottom. Thanks for the help guys, love the support! Cheers.

 * The solutions in the above posts by dieterich and Viper007Bond worked for me 
   as well. (I’m running WordPress 2.0 under IIS). Thanks very much.

 * I have a question, we did the fix but still plug ins arent working.
 * 1. should this be done after uninstalling the plugins or does it matter?
 * 2. once the patch is run should i uninstall and reinstall the plug ins?

 * I’ve tried the solutions in this thread as well as adding the lines
 * `set_magic_quotes_runtime('0');
    ini_set("magic_quotes_gpc","0");
 * to wp-config.php and I still have plugins that won’t activate or deactivate. 
   I’ve deleted many of them and still no luck. Anyone else find a different solution?
