Hi guys, here is another easy fix for the next version. Currently when you are setting up the admin js and css files you use get_bloginfo('url'). Unfortunately fetching the site URL that way does not account for SSL admin setups, and the files end up causing 'mixed content' errors because they are not loaded over HTTPS.
The solution is simple, just use site_url() instead. It gives the url of the site, as well as switching http:// to https:// if is_ssl(). It's the new standard way of doing it and it really works a lot better and makes more sense than get_bloginfo.
I'd recommend testing your plugins with SSL generally to make sure there are no mixed content errors. There may be others I'm just not noticing yet.
