Getting a 404 error after switching to php4

[insomn3ak]

I'm able to access webpages fine when using php5, but I need to use php4. After switching to php4, I get a 404 error.
I've set up virtual hosts in both the httpd5.conf and httpd4.conf but I get different results.
Very confusing but I know I'm probably missing something obvious.

Ok, this is really wierd...I've noticed that the httpd4.conf file keeps reverting back to an older version somehow. I'm certain that I have changed and updated it, but somehow my changes keep getting deleted.
Any ideas??
