Update profile blank page
Hello I am getting a blank page upon updating page. I have identified the plugin that is causing this (NinjaForms file upload extension). I am not using the plugin on the update profile page, but for some reason it is still causing the issue, as if I deactivate it the update profile page function works. However, deactivating this plugin is not currently an option as I need file upload functionality on several of the forms I use elsewhere on the site.
Plugin devs are saying it is a theme issue, so I was hoping maybe someone on here might know a fix. Error code below.
