It looks like you’re using a very old version of Ninja Forms (v3.4.24.3). Please update to the latest version, 3.13.2, and the form export functionality should work properly.
To manually update the Ninja Forms plugin, first download the latest version from https://downloads.wordpress.org/plugin/ninja-forms.3.13.2.zip. Then, go to WordPress Dashboard → Plugins → Add New Plugin and upload it. When prompted to replace the old version, confirm the action. This process ensures you have the latest copy of the plugin without any corrupted files.
Then recheck it, and if it still doesn’t work, open a support ticket through their support channel here: https://ninjaforms.com/contact/
