Changed hosts, theme options stuck :(

Hello, all!
Here is the problem site: https://vanquiscreditcard.net/
It has recently changed ownership AND hosting accounts. I need to change Google Adsense code all the way through the site. I managed to do it in posts and pages, but I am completely stuck in theme options ?? The problem is right sidebar Google ad. It is Weekly theme. In Weekly theme options it is inserted into Advertisement widget. I have changed this widget to my Adsense code, but on page it does NOT change! ??
Is there any way to edit it right in my host cPanel somewhere in files? Or any other ways? Please, help!
