[Plugin: Protection WP] Recent update disabled RSS

Hi,

Great plugin!

I am experiencing a problem after your update and with WordPress.

Please view

Then click subscribe,My Subscribe to blog link no longer works. It is reverting to http://supplyanddemand.us/blog instead of http://supplyanddemand.us/blog/feed.
Nothing was changed in my theme.
I tried disabling plugin.
Deleting plugin.

The same thing happens.

Your thoughts on correcting this?
