We have a dedicated server running plesk using FreeBSD. After I installed plesk and have it turned on, I can use IE to pull out the site, and I do see the page generated by plesk.

the second day, it'll have a page not found error. so I shut down plesk and restart again, still have a page not found.

so I downloaded apache2 and installed it separately. have it up running and I am able to view the site. trned it off

then I turned plesk on again, and the plesk generated page is back up.

I am thinking it's probably a port conflic or some kind of conflict so when plesk settles down, I'm not able to view the site.

any ideas?
