Plugins not showing in Admin I'm experiencing a problem where none of the plugins (2 captchas, and a random bookworm plugin) are showing up in my admin panel. 

Folders are lowercase. 

I've also checked permissions; folders are at 755. The corresponding file is at 644.

I have the Pixel &amp; Tonic Contact Form plus the RetconHTML plugins currently in there, so I know I've successfully uploaded plugins before. Just not sure what's going on.

Thoughts?

-edit-

The two plugins I'm currently having problems with are bookworm and recaptcha, not anything I've specifically developed.

Here's a screenshot of my plugins directory:
Probably the name of the folder isn't the plugin handle. Check inside the plugin's folder to see if the actual plugin folder is inside there. For instance:

forge@nys-production ~/nystudio107.com/craft/plugins (master) $ tree -L 1 craft-typogrify/
craft-typogrify/
├── readme.md
└── typogrify


In this case, when the plugin is downloaded or cloned, the name of the folder is craft-typogrify but the actual plugin folder is inside of this folder, and is named as a lowercase version of the plugin handle: typogrify.

This is what needs to be directly in the craft/plugins folder for Craft to see it.
