Single letter "n" in Welcome Area

Hi, after working several days hard on this theme I noticed that at the top of the welcome area there is a line with a single letter.
The site is www.pclineweb.it
Someone kwown how to remove the line?

Hello there,

I can’t reproduce such that issue on my test site. I noticed your site is running several plugins. One of which might be the source of the trouble. Please try deactivating them. If it resolves the issue, you can re-activate them one by one to find which one contains that “n” letter. If it doesn’t give any different, please try installing the fresh one of Moesia.

thanks for your reply, after several attempts I decided to restore a backup that I had done days ago, problem solved

My pleasure. Great you figured it out.
