not parsing sometimes

i have the latest ver of apache and php 4.0.1pl2. lately i'm having a problem with PHP not parsing the code in my pages...instead of parsing it it just displays the HTML....it seems to do this only with include and require statements......the logic part of pages seems to work ok....... any ideas? ~kurth Kurth Bemis - Network/Systems Administrator, USAExpress.net/Ozone Computer kurth@usaexpress.net http://www.usaexpress.net/kurth ICQ - 6624050 Call Sign - N1TYW PGP key available - http://www.usaexpress.net/kurth/pgp Fight Weak Encryption!
