[SOLVED] Strange css color override

Hi!

Im working on a new template and there is one problem involving Youjoomladate extension (and only this extension, as far as I can see). The date itself is displayed correctly, but somehow it influences surrounding elements.

If youjoomladate is enabled, the article does not use the background color from .contentpaneopen css element (as supposed to), but black background, which happens to be the background color of the date component itself. After some testing, Ive found out that this background color comes from the body css element (which also happens to be black).

Now, if I disable youjoomladate, the article takes the background color from .contentpaneopen css element, as expected.

What am I missing?
