Mobile menu written vertically and unreadable/unreachable/out of screen

Hello, I'm using Bold Photography Free theme. In the mobile version, the dropdown menu doesn't show on display as in the mobile DEMO of the theme, but rather appears with words written vertically. Plus, it's at the very top right side of the screen, partially off-screen, almost unreachable to press. Here is a screenshot of the issue: https://ibb.co/Jv7JL8v here is my website: https://ravencloud.rocks/ I need to present this website tomorrow evening as the final project work of an exam for university, so I would really appreciate if you could please help me out solving this problem ASAP. Many thanks in advance
