WordPress MU

hey, so i've tried to add a few regular wordpress plugins to the mu-plugins folder, and they don't seem to be working.

the reason I know they're not working is that the plugins have admin settings menus that don't appear in the backend when i put them in the mu-plugins folder. (they do appear when I put them in the regular plugins folder and activate them)

Am i doing something wrong, or will these just not work sitewide?

plugins with sub folders don't work in mu-plugins. But usually you can put the plugin.php file directly in mu-plugins and leave the folder intact. The plugin might need edits for the correct paths etc

For example, with WP-Super Cache upload the wp-super-cache folder to mu-plugins then move wp-cache.php out of it and put it in mu-plugins.

got it, thx!...is there a WPMU version of this: WP_PLUGIN_DIR ?

so I know how to edit for the correct path...

Also, if a plugin has settings, will they appear in the admin menu and work across all blogs?

Depends on how you want to use the plugin. If you dont want users to see it, then edit the plugin and move the menu under Site Admin.

is there an easy way for you to tell me how to move the menu? (I'm only a beginner with php)...:)

Everything u need to know:

Examine other plugins and see how to do it.

thanks! I'll do my best...
