My blog's background image used to repeat and now, suddenly, does not. The blog is here: http://bilinguish.wordpress.com/ and I am using the theme Enterprise with 5 widgets. As you scroll down the page, the image was tiled so that when you reached the bottom of the picture (ocean) it started again with the top of the picture (sky). Today I changed one of the widgets, and now the picture no longer repeats. When you get to the bottom of it there is just blank space. I hadn't made any changes to the page that controls the background image, but after noticing the problem I went and tried to fool around with the settings, changing it from "tile" to "tile vertically" and so on, but with no success. I'm not sure what I did to cause the background picture to stop repeating, but I would like to undo it. Any advice is appreciated.
The blog I need help with is bilinguish.wordpress.com.
