Form token expired | WordPress.org

I use the Formidable plugin on my website. Recently there is an issue with my contact form. When you want to submit the form the error “Form token expired – refresh page” occurs. Can you tell me if this error is about nonce or not? An what nonce name is being used on that form?

It most likely has something to do with the Litespeed Cache plugin. I already contacted the support and they wanted me to ask you about the nonce ).

If there is anything else you know about how to solve this issue please let me know.

Thank you.
