Major issue with Woo Commerce

Hello, I am having major issues with my Venice Lite theme. I have contacted Bluehost, and they suggested I contact the developer and explain that there are numerous errors with the Woo Commerce plugin. I have deactivated my Woo Commerce plugin, but the errors with the Woo Commerce persist on my website. Also, I am unable to update my Venice Lite theme and am running on a very old version. The only page that works on my website is the homepage, then unable to go to any other page, or post on my blogsite. I hope someone can help me with this! I would rather not redesign my website or use another theme. Thank you in advance, msdarcyonline.com
