I tried it again on your recommendation. As soon as I installed it my site went down. I had to manually uninstall it after that. Failure to modify header issues came up, and when that happens, one must go to the drive on the server and manually delete the plugin, as you lose admin access behind WP and everything else. I will not use your plugin again, nor be tricked into installing it for you either lol. Your plugin is crap in my book. Others may like it, but it doesn't work for me. I know it's conflicting with another plugin I am sure, but I am not deleting plugins I use just to use your widget. I just don't need it that badly, nor do I need the hassles of playing beta tester for you either. I got the api key in advance of the install, and it started telling me header problems as soon as I installed it, and then install the key messages came up, which you can't even do when modified header issues come up, as it shuts down the whole admin back end, so its a worthless plugin/widget in my book based on that. Api keys are truly a waste of time, and while you all may need them, I don't. Its a widget, not a major component to WP, screw the api key, its a stupid widget.
Chacha=CRAPCHA Only my opinion of course. YMMV. Good luck to you either way.
