perch_forms() not being found with v3.0

For my latest project we are using the newest version of perch, but the perch forms won't submit, and the php_error.log says that the function cannot be found:

PHP Fatal error:  Uncaught Error: Call to undefined function perch_forms()

I had a similiar problem with the blog app, but when I reinstalled the files it started to work. I have done the same with the forms, but still the same error.

Here is the diagnostics:

The form is a simple contact form, no file uploads or anything.

Is perch forms handled differently in the new version?

edit: I also get this from the debugger on the perch forms section in the dashboard:
