I just upgraded a Tiki wiki from version 3.0 to 15.5 (!!!). Amazingly, to me anyway, it seemed to go incredibly smoothly.
That is, until I wanted to set some of the Admin settings.
I do see, in Menu > Settings, a list of pages, almost all of which I CAN access. BUT, when I click on "Control Panels," which is equivalent to:
all I get is a completely blank page.
Any idea what could be causing this and what the fix might be?
Thanks in advance!
