[pmwiki-users] pmwiki-based site is broken

[Mark Lee]

I cloned my pmwiki-based site from one host to another. My cloned site is
working fine. The original site is broken. As I was modifying files for the
new site, I think I accidentally saved a modified file to the orginal site.
I don't know where to start trying to fix this. Can you tell what is wrong
from the warnings being produced? A subset is pasted below:
