[pmwiki-users] Users not logged in get a blank page

Completely blank pages without any message often are caused by a call to
a function that is not defined - either mis-typed or deprecated/removed.
I'd review all files in the "local" directory if some of them, notably
those starting with "Engine" and "Main", make some suspicions calls.
Otherwise, see the page Troubleshooting in the documentation -- it can
be an older addon that calls an undefined function, or that calls
htmlspecialchars(). Troubleshooting contains instructions on how to
track the cause:
First section for tracking, see also the section on blank pages near the
middle of that page.
