PFMaBiSmAd Posted December 10, 2008 Share Posted December 10, 2008 When the error refers to output at line 1 and you have removed or determined there is nothing before the <?php tag, your file is probably saved in UTF-8 encoding and the BOM (Byte Order Mark) characters at the start of the file is content sent to the browser and prevents headers from working. Save your file as ANSI/ASCII or if you must save it as UTF-8, save it without the BOM.

PFMaBiSmAd Posted December 10, 2008 Share Posted December 10, 2008 You either have content/characters before <?php or the BOM characters. If you tried to save the file without the BOM and you still got the error, then either that did not work or the file was not uploaded correctly onto the web server. Try it again. How are you uploading the file to the web server? If using FTP, make sure you are using ASCII mode and not binary mode.
