Hello there,
We use one layer of security to our ajax request which is WP Nonce – but due to caching mechanism from third party plugins/hosting this security nonce also cached which cause this error “something went wrong, please try again after some time”, some cases by setting up cache timeout in plugin settings reduce this kind of issue.
We have alternate solution of nonce for security, which is google reCAPTCHA v2 checkbox. You need to enable the google reCAPTCHA settings followed by site key and secret key in our settings page, also enable Server Side Validation checkbox as well. Once you’re configured properly instead of nonce it will be google reCAPTCHA response and rest everything works the way it should.
Let us know.
Thanks.
