Plugin not showing up in CP I'm attempting to install the Contact Form plugin. I believe that I've uploaded the correct folder to the correct location, but it's not showing up in the control panel. I'm relatively new to Craft, so this is the first plugin that I've installed.

This is my folder structure: 



I've seen a couple questions that indicate that the most common problem is improper capitalization on the plugin folder. However, as you can see, mine is all lower case. 

I'm building this site on a Linux localhost and I've even gone so far as to chmod 777 plugins -R just to be sure it's not a permissions issue. 

I've made sure to clear caches after every change, but no matter what I do I can not get the plugin to show up in the CP. 

What else should I look at to diagnose and fix this?
Well, I deleted the whole contactform folder, downloaded it again, and added it back to the plugins folder. Just to be safe, I ran service httpd restart. After that, it showed up immediately. 

I can't be sure, but I'm assuming that there was just something wrong with the originally downloaded files. 

I hope this helps someone else in the future.
