Hi
I updated something by mistake, now I get these warnings:
(url is : http://www.goldpharm.co.il/ )

Warning: Cannot modify header information - headers already sent by (output started at /home/goldphar/public_html/classes/Tools.php:1) in /home/goldphar/public_html/header.php on line 3

This is most likely because you're echo-ing out stuff before you're header() statement.

Remember that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP. It is a very common error to read code with include(), or require(), functions, or another file access function, and have spaces or empty lines that are output before header() is called. The same problem exists when using a single PHP/HTML file.

<html>
<?php
/* This will give an error. Note the output
 * above, which is before the header() call */
header('Location: http://www.example.com/');
?>

<?php
echo "something";
/* This will also give an error. Note the output
 * above, which is before the header() call */
header('Location: http://www.example.com/');
?>

Ouch! Use code tags! That's the [ CODE ] button in the editor.
I assume that this code isn't yours. There's a marked discrepancy between the maturity of the code and your question.

Sorry, fixed the code above,
Yes this is prestashop code (open source),

And I probably messed something up , (sure feel stupid).

what can I do?
