Thank you for creating such a useful plugin and sharing it.
I got the following alert when I tried to activate the plugin.
The plugin generated 440 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.
While I am able to test the plugin on the site, I also found I am experiencing problems when adding a block of 125x125 ads in 2 columns. The wrapper doesn't seem to wrap the ads. (As seen here http://188.8.131.52/asa/ - scroll down the sidebar).
Any advice or direction would be much appreciated. Thank you. :)
