Support » Plugin: Ninja Forms - The Easy and Powerful Forms Builder » Error after activating ninja forms

  • Resolved silentbob38



    I have just upgraded my wp site to the latest version and I then I updated ninja forms. I had to do this manually by copying the downloaded plugin over to my site.

    I then tried to activate ninja form using the admin console but the page goes to a http 500 error.

    looking in my error log for the wp site I get the following message.

    [04-Apr-2017 09:49:10 UTC] PHP Fatal error: Uncaught Error: Call to undefined function ninja_forms_register_field() in D:\Mywpsite\wp-content\plugins\ninja-forms\includes\fields\calc.php:53

    Can anyone help?
