Good evening, dear sirs,
I would like to ask your help please for 3 situations in the theme SNS ANTON.
I send 1 photo to see how they can help.

The number two in the pic, I would like to know how I can eliminate this menu or just change the language, I already looked in Menus, Widget, I can’t find it, nor to delete or edit it.

The number three in the pic, I would like to know how I can adjust all of your content inside the page, everything is very close to the margins, only the home page is not like that.
I have already tried to go to the WP panel / pages / choose the page and edit / but I have no option to adjust the page width, it is always in the default model.

Finally, the number one in the pic, I would like to know how I can change the language in these fields, I can edit your content but not change the language where it says “Phone” and “email”. I want to change not the content but the name of “phone and email” to something else.

Thank you very much for your help, I look forward to help.
Compliments
Ricardo Sousa
