How to remove line around shape in illustrator

[Yun5EDB]

Hey guys, as you can see there is a black line around every shape, but it's not the border, since I've made my border color into none and the stroke panel is not activated. Anyone know what kind of line is this and how to get rid of it?

Check your appearance panel. You may simply have applied multiple strokes and a global one applied to a group outlining all your shapes.

Look for a solid radio button on the group or layer associated with your artwork. If present, you can drag it to the trash icon at the bottom of the Layer Panel to delete it.
