Forbidden Error on Donation Submission During Test using Test Donation Option

Hello Team,

We installed the GiveWP plugin and set up the v3 visual builder form on our site, configuring the default test donation for testing. During testing, we found that after submitting the form, it throws a forbidden error. Following is the error screenshot for the reference – https://tinyurl.com/2ccz5ma5

#1 Give WP – Version 3.16.2
#2 WordPress – Current version: 6.6.2
#3 PHP Version – 8.2.12

Thanks!
