Short description of error
Looks like it's using the old matrix mult syntax.. should be an easy one char fix :)

Traceback (most recent call last):
  File "e:\blender-2.80\2.80\scripts\addons\mesh_looptools.py", line 3777, in invoke
    return self.execute(context)
  File "e:\blender-2.80\2.80\scripts\addons\mesh_looptools.py", line 3800, in execute
    object=object)
  File "e:\blender-2.80\2.80\scripts\addons\mesh_looptools.py", line 302, in calculate_plane
    normal = rotation * mathutils.Vector((0.0, 0.0, 1.0))
TypeError: Element-wise multiplication: not supported between 'Matrix' and 'Vector' types

location: <unknown location>:-1

Exact steps for others to reproduce the error

Make sure the Loop Tools addon is enabled
Select a Face
Expand the "Flatten" rollout
Change Plane to "View"
Click "Flatten"
