Hi we have contacted the support on Woofunnels because we experienced some errors on on Checkout Page. They emailed us and it says:
Sorry for the delay in response here.
We found the core reason for this failure, its because of this script embedded in the checkout settings
You can see in the screenshot that this request to save settings with this script is failing as the Cloudflare firewall prevent this call to run.
This is why the ‘Save Settings’ call is failing because the call is blocked by the Cloudflare script.
I think you should contact Cloudflare support in order to get a solution for not to block the API Call.
Hope it helps. Let us know if any further queries."
Please help us on this matter. Thank you!
