Error when activating litespeed

Hello, I would really like your help.

I use the “CheckoutWC” checkout in my woocommerce store.
https://www.gplvault.com/product/checkoutwc/

When activating the litespeed′s cache, the attached print error occurs and it is not possible to continue finishing.

When I disable just the litespeed′s cache, the error does not occur and the checkout works normally.
