WordPress nonce 403 error

Hello!

I’m facing this problem with my plugin Convert Pro. When our users submit the forms they get 403 forbidden error. When I clear the cache the forms start working properly again.

I looked into your support tickets and found that reducing the expiry time to 10 hours resolved the issue.

I have set the expiry to 10 hours and waiting for my clients to see if they face the problem again or not?

Now, my question is that one of our clients has both AO(Autoptimize) & WP Fastest Cache plugin installed on his website.

When I clear the cache WP Fastest cache the forms start working and also when I clear the cache of AO the forms start working. Any idea why clearing the cache of AO works? When I clear the cache of AO does it also clear WP Fastest cache?

Looking forward to your response.

Regards,
Premanshu
