PHP error FastCGI - sessions is not within allowed path(s)

[lauras]

Describe the bug

Find these errors in PHP error logs. (File attached.) php error logs re pods.txt

I have not noticed any functional problems with Pods so far though. (There is a conflict with Ninja Forms, which I filed as a separate issue. That conflict does not generate PHP errors.)

To Reproduce Steps to reproduce the behavior:

1. Go to any Pods Admin screen
2. Error appears in logs

Expected behavior No PHP errors.
