Cannot send session cookie / Cannot modify header information

[witch-of-germany]

Urgent help needed!

I was testing a new customer site (to be found at www.nicholasdesign.biz/NicholasDesign) yesterday. After adding a new customer, I received the message that the table ndzen_customers does not exist. That is true, because the database tables are ALL all called zen_ (ndzen_ was an earlier version). Searching for ndzen_ using the Developer Toolkit, I found it in ONLY TWO files: includes/classes/shopping-cart.php and functions/function-prices.php.

Thinking this was an easy thing to sort out, I changed the occurences of ndzen_ to zen_ . But the SH... started happening. On the shop site, I now have the messages:

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /www/htdocs/w0088607/NicholasDesign/includes/classes/shopping_cart.php:2) in /www/htdocs/w0088607/NicholasDesign/includes/functions/sessions.php on line 108

In addition, I cannot access http://www.nicholasdesign.biz/NicholasDesign/admin anymore, either because of similar problems. What should I do???

Done! The reason was an extra line in the file ...

I just transferred my site to a new hosting company and get these warnings now. Extra line where? Beginning or end? How could that happen? Did perhaps my hosting company screw up the edit when they changed configure.php? Any ideas?

Ah! It was a single blank line at the end of configure.php they edited.
Fixed.

Hate when that happens ... thanks for the update as that will surely be of help to others!

HELP.
I'm having the same issues but I have no spaces or blank lines in my files. Here are my error messages:

It all began when I turned ssl enabled to "true" - I saw the errors right away and switched them back to false...but the errors are still there! I'm completely lost as line 1 is perfect for both configure.php files.

SOMEBODY PLEASE HELP!
