Cannot enable Craft plugin in control panel
My guess is it's a case sensitivity issue with the main plugin class/file name (some operating systems have case sensitive filesystems and some don't).

You can review the requirements for how things should be named here: https://craftcms.com/docs/plugins/setting-things-up

Or better yet, use a site like https://pluginfactory.io/ to generate the boilerplate plugin code for you and compare it to what you have.
