What files does this plugin add to?

Hi guys.
I hope you can help.

I was trying to set up a free ssl via cloudflare and used this plugin to finish the process based on guides i had seen. As soon as i activated the plugin, i got locked out of my dashboard. Panicking, i deleted the plugin from the ftp and tried to delete any code it spilled into .php files – but nothing seems to work [i have backups of all edited files]. I have deleted my site from cloudflare altogether and still nothing.

I was just wondering if there was any obvious places to modify files for traces of left over code? it seems like my site is still being forced into https.

thanks!
