Problems with WordPress wehen I activate SiteOrigin Widgets Bundle

Hi staff,

i have some problems when i activate your plug in:
i can’t visualize in the correct way wordpress, no icons, no flag, for instance.
then i can’t use the button to add link un the editor, i can’t add the main image to a post.
When i deactivate the plug in everything works perfect.
I really love you plug in and i would not disinstall it.
Can you help me ti solve this problem?

Thanks a lot.
