Zoho Breaks My Other PHP Web Pages On Bluehost

Zoho Breaks My Other PHP Web Pages On Bluehost

Finally got Zoho working great on Bluehost. But now when zoho is running none of my php web pages work.

Has anyone else had this this problem.

The error I get in the error_log is "Premature end of script headers"

Note, when I stop the zoho service, the other web pages are working correctly.

I'm also able to serve non php web pages just fine.

I'm running php 4.4.4
