 * Hi [@mohobook](https://wordpress.org/support/users/mohobook/),
 * Thanks for reaching out!
 * Most of the time, the security issue occurs because the WPForms nonce is corrupted.
   The nonce is a security feature in WPForms ([screenshot](https://a.supportally.com/i/FTb4aX)).
 * Please access your form in an incognito window or a new browser to see if the
   issue is related to your browser cache.
 * If the issue persists in an incognito window or a new browser, please provide
   your form URL so I can access your form and provide further information regarding
   the issue.
 * If you have any questions, please feel free to let me know.
 * Thanks!

 * Hi [@mohobook](https://wordpress.org/support/users/mohobook/),
 * I’m glad to hear the issue didn’t occur in an incognito window.
 * So, it’s likely that the form was open for too long before submitting, which 
   invalidated the WPForms nonce and displayed that error alert.
 * If you’d like more help with using WPForms Lite, please feel free to reach out.
 * Thanks!
