HELP SOON, PLEASE – Issues with Woocommerce blocks and font sizes

Hello,

I hope that all is well.

I am setting up my first WooCommerce shop page on a website made with the Blur theme. My friend wants/needs this site to launch this weekend (Jan 5th or 6th at the latest.) But I am having some problems with my shop set up/ formatting.

Where I need help most is with these pages: the cart and the shop page.

My issues are:

• I can’t use my custom template for my Shop page. Whenever I change and apply the new template in the Pages area on the dashboard, the template automatically goes back to default. I’m not sure what the default template for the Shop page is. (I think it’s the Product Catalog template?)
• The font is too small for all my cart items and order summary sections on the Cart page. I tried to add custom CSS to fix this, but I could only fix the product description. Nothing else changed.

I’ve disabled and deleted various plugins, cleared my cache, removed and restored pages, but I can’t fix my problems.

Should I just switch themes and start over? If so, could you please recommend a free block theme for me? I haven’t learned to use the customise menu yet.

Thank you so much for your time, consideration, and any help you are willing to provide! Have a lovely day and a great new year!

Kind regards always,

Nicole
