qtranslate plugin issue with the appearance of the flags

Hi, I think this issue is related to the theme because it doesn't happen in other sites with other themes.
See image attached. I'm using a widget in the footer area, and I would like to remove that doted inclined lines at the left of the flags. Is that possible?
Thanks

Hello,

Paste this code in Custom CSS

Code:

.footer .footer_widget ul li {
background: none;
}

 

Thanks a lot, it worked perfectly
