Show IP address

I thought I would create a simple plugin,that does what its meant to do, it's simple and it works.
Working on a few issues to do with 'shell_exec()' but apart from that it works.



A work in progress

UPDATE:  Developer fixed problem so I am changing my 1-star review to 5-stars as it is working great now.  Thank you!

Can not activate the plugin.  When I try I get the following message:
The plugin does not have a valid header.



Developer fixed "invalid header" problem

A simple plugin to show your visitor’s IP address on pages, posts, widgets, and the admin dashboard. Lightweight and easy to use.
