I had a problem with errors that indicated that a variable or object wasn't
declared when, looking at the source, it clearly was (in an included file). The
two occasions that caused me problems involved variables or objects that had
been added since my previous update from CVS.

My theory was (and still is) this:

If a page changed, phpa recompiled it. However, if a file that was
"included/required" into another file changed, it wasn't recompiled. I never did
the necessary research or troubleshooting to prove my theory, because it wasn't
too difficult to restart phpa from scratch (stop apache, flush the phpa cache,
delete temp phpa files, and restart apache), and it seemed to fix the problem.

hth,
Rick
