Ninja Forms has changed a lot over the years. While doing our best to maintain backwards compatibility where possible, there comes a time when deprecated code should be removed to prevent plugin bloat. If you are updating from a very old version of Ninja Forms, you may experience issues updating directly to the newest version. In these instances, your best option is incremental upgrades to ensure When updating Ninja Forms from very old versions (more than a year old), your best option is incremental upgrades to each major release version.
Below, we have listed each major version of Ninja Forms prior to what is currently available on the WordPress repo. Find the version your site is/was running, and install it from this page. Then, update one at a time to each higher version until you get to the most recent on this page (Ninja Forms Version 2.9). Once you are on that version, you should be okay to install the most recent version from your WordPress dashboard.
