Find Error (WordPress, Enfold, Form, Recaptcha V3, Nonces, Caching) and fix it

Dear Freelancer, We are looking for a freelancer who can solve the following problems in a goal-oriented and honest way. We expect to find the error and at best solution strategies. Marginal data: WordPress with Theme Enfold (the latest versions) With and without a caching system, various customer sites display this message when filling out the theme's own contact form with reCAPTCHA V3 after a few hours when submitting: "Sorry, but the session time for this page has expired. Please reload the page. WP Nonce Check Failed" You will get an Enfold-Theme, where you can do test and a URL, where you can see the error. Enfold has inside also a Caching and Combining system. If this turned ON, the error occurred. Turned OFF, the error is today not visible. With Caching Plugins as WP-Rocket and Fastest Cache, the error occur also. No solution like: child-theme with [login to view URL] change, please. If something must change, we need update-secured solutions. Please only bid if you have experience with the theme and are at best familiar with reCAPTCHA, Enfold, Caching (and of course JS and co.) Please: If you just want to earn money on your own and don't want to burn for the cause or simply don't have any experience or ideas: Please: Don't waste our lifetime and energy together. Please only bidders who really have what it takes. In the best Case: You wrote in the beginning "Enfold-recaptcha-Expert" instead of auto-filled text, what was your past web design projects, which isn't helpful at this stage. Best R.
