Answer for Bugs in contact form and newsletter

Hello, for the contact problem, I need you provide your PHP version. For the newsletter issue, MailChimp API sends request through CURL, so make sure you have enabled CURL in your PHP. And the secondary menu is only displayed on non-frontpage, it seems that you just have only frontpage now.
It’s complex to solve all problems, your patience is needed. I’ll try my best to help you. Thanks!
