Made the Switch to 2.0 and no sidebar menu

[episodeboutique]

Hi there! My name is Belle and I recently made the switch to a version 2.0 theme. For some reason, my sidebar menu will not show up and Im wondering if its something to do with the code. I purchased this theme via creative market. Wondering if anyone can give me a sample of their code for the sidebar menu so I may compare and continue. 

Thank you!! 

All my best,

Belle
