TOPIC: Can't Save Projects

WordPress version: 4.5

I've installed Portfolio Manager, created my API key and entered it. I've created a category, and when I go to add a new project I enter the Behance ID of the project I want to add, and it finds it without a problem.

Now I click Save & Close and I get redirected to my website with a 404 Error Page. Not exactly sure why this is happening, but I've tried searching on Google to see if anything comes up from others with the same problem and I haven't found anything.

Does anyone maybe have an idea what it could be? I love the idea of this plugin, but I'm not able to use it completely as of right now.
