I was able to get this fixed by just going in and typing editing the custom widget's .aspx file to show the following:
Background: none;
I however am brand new to LanSweeper and am wondering where in the .aspx I can make the URL go to forcast.io's information and have it be a regular widget as opposed to having to input the URL for each user who wants that custom widget.
Sorry to bring up an old post, but this one seems to be pretty helpful.
