404 error for background gradients + G-analytics

Hey,

i get 404 error for all graphics are stored unter theme/images/background-images/
I look and i found that the url structure is incorrect.

Its https://my-domain.de/wp-content/uploads/dynamic_avia/my-domain.de/wp-content/themes/fb-theme/images/background-images/gradient-bottom-dark.png
But this structure comes from enfold. How I can repair this? Is this because i rename the themefolder to fb-theme??

Next problem is google analytics. I switch code to universal analytics and now my tracking is broken. I paste the code in private area.
