Plugins not showing in Admin

Question

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 & 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:

Answer 1

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.

Answer 2

I'm an idiot.

In the Settings area, I was expecting the plugin to show up in the Plugin section after uploading. Don't know why, but noticed last night that under the System section, there was a plugin option there. Once I went in there, and actually installed the plugin, it showed up under the Plugins section.

sheesh
