@vincenzost Just delete line 245 in …/wp-content/plugins/ninja-forms/includes/Admin/CPT/Submission.php and it will work fine with PHP 8.3/8.3.1

Just delete duplicate ‘static variable $fields’, that is, remove line 245 and it should work just fine.

Same…

Ninja Forms Version: 3.7.0
Fatal Error in PHP 8.3
PHP Fatal error: Duplicate declaration of static variable $fields in /wp-content/plugins/ninja-forms/includes/Admin/CPT/Submission.php on line 245

Thanks again for pointing me to the right direction. That did the trick.

Thank you for the quick reply. I’ll try that and report back.
