Some issues I can't figure out

Hi there,

I have been struggling wtih this theme for a week now. I made some translations and configured theme. However, there are sittl many items that I couldn’t figure out how to handle.

First,

I need to resize sidebar or subscribe widget so that it fits into sidebar. Right now it is out of sidebar border.

Second,
Subscrice widget cannot be translated? I have trasnlated almost 90 percent of my theme into Turkish. But there is this sentece saying “Subscribe Now” that I couldn’t find under general settings/language. How am i supposed to translate this sentence?

Third,
I cant find where to change main background of the theme. I have been uploading some Jpg file to “Website Background” under layout blocks, yet nothing changes. It is still gray and I cant even change it to another color.

Any help is much appreciated.
