I have recently given a control of newly bought hosting space and the domain account. There is a technical team from the hosting site to help out with problems, but that is a long process, i.e. log a ticket, wait for a long time, and I don't get the correct answer in the first shot.

I was wondering, if anyone has any helpful guide and how one must go with hosting a site. Any info that must be know w.r.t to cpanel? Any other useful stuff if any one has, or could point me to ?

Just to give a few difficulties:

1. The same php code working well on local machine, giving error on remote as "File not found". The file is present indeed as I have ftp'ed all the files correctly.

2. session_start error are outputted to html page with warning "Header already sent".

and many more technical things, that work well on local but not on actual hosting server.

So, if anyone has any helpful stuff in this reference, as to what all changes are required or what a programmer must be aware from a hosting perspective, please let me know.

Note I am hosting a PHP site with mysql db, on a shared environment.
