That means that you have sent output to the screen.

Check the version of PHP and MySQL on the server.

Make sure all files are saved without the BOM

Also make sure not to have white space in the files

Make sure not to include the endding php tag.

What did you Try? What did you Get? What did you Expect?

No, it means the server doesn't have mysqlnd and/or the PHP mysqli extension installed.
The "headers already sent" notice is a side-effect, because the actual error message counts as output.

Thanks Narf, that's one reason I mentioned to see what versions were installed, I thought all web host had them installed by default.

I know my web provider has them all installed.
