Problem with editing the style

Hey,there!
I have recently made a forum and I wanted to change the style! I'm using the colors of the "Beach" style,and the pictures of the "Gothic" style. I have started uploading my own pictures and everything started perfectly...exept that I can't change some stuff.... the buttons (log in;profile;members etc.) & a line,that just stands there...I've searched for it to change it...but I can't find it on the style in my admin panel...
Here,take a look:
-> Here on the right <-
I will be really happy if someone could help me fix those!

Thanks in advance and sorry if I have any spelling mistakes!

Hi,
Follow this :
Go to Admin Panel
Styles Admin
Picture and colors
General/Explore
thre you can change the buttons

Thank you so much!
