I found this script on a code site and borrowed it / modified it some. This script is suppose to take the data from a table and let you download it as a excel / doc file, however I keep getting header errors. This is the code : The problem is this: I get a bunch of errors Warning: Cannot modify header information - headers already sent by (output started at /home/webmesto/public_html/test/excel2.php:1) in /home/webmesto/public_html/test/excel2.php on line 49 Warning: Cannot modify header information - headers already sent by (output started at /home/webmesto/public_html/test/excel2.php:1) in /home/webmesto/public_html/test/excel2.php on line 50 Warning: Cannot modify header information - headers already sent by (output started at /home/webmesto/public_html/test/excel2.php:1) in /home/webmesto/public_html/test/excel2.php on line 51 Warning: Cannot modify header information - headers already sent by (output started at /home/webmesto/public_html/test/excel2.php:1) in /home/webmesto/public_html/test/excel2.php on line 52 I'm pretty sure the error is where the headers are processed here: But I'm not sure whats wrong. Would this be an issue with a security feature on the server? Anyone have any ideas?? Running PHP5 / Mysql 4.1 RHEL 5. Thanks in advance!

When I had some errors, what I normally did was go to php.ini, change the config to display errors only. After that the scripts worked and never seemed to have problems. I may be missing out something but at least the script runs without errors (or rather there are invisible).
