Hello,
I see you are encountering deprecated warnings related to dynamic properties in Ninja Forms. While disabling E_DEPRECATED or E_USER_DEPRECATED in error_reporting might suppress these warnings, it’s important to consider the long-term implications.
Before making any code changes, I recommend checking the PHP version you are running. Older versions of Ninja Forms may not be fully compatible with the latest PHP versions, which can lead to deprecated warnings.
If you’re running an older version of Ninja Forms, consider updating it to the latest version. Maintaining compatibility with the latest PHP versions is essential for security and performance, so it’s a good practice to keep Ninja Forms and PHP up to date.
If that doesn’t resolve it I recommend reaching out to our Customer Success team. They will have an official fix or guidance on how to handle this situation properly.
