Shipping Calculator Issue

Hi I am using Fashe on my site
but the shipping calculator is displaying code as an output when I test it. How do I solve this issue? I can’t find any obvious problems in the code, and I haven’t edited any of the shipping calculator or cart coding.

Thanks in advance,

Hi there

this is the first time such a problem is appearing, are you using the latest version of the theme? any modifications in the theme files?
