Both fxCommon.php and index.htm do exist.
The problem is not changing the DOCUMENT ROOT.

Document root is/home/timismor/public_html
5 /home/timismor/public_html/fxCommon.php exists
12 /home/timismor/public_html/index.htm exists

>17 Switching Document root from timismor to timism

Document root is/home/timismor/public_html
25 /home/timism/public_html/fxCommon.php no exist
[I don't think #25 is valid, but a reflection of a bad DOCUMENT ROOT

32 /home/timism/public_html/index.htm no exist
