Hi @kevinebra,

This bug tracker is for core bugs with WordPress, not for support such as this. However, the problem you're experiencing is most likely due to a blank line, tab, or other character having been accidentally inserted onto the very first line in your wp-config.php file.

For any further assistance, feel free to open a thread on the ​WordPress.org support forums.

output started at wp-config.php:1 is most likely a ​byte order mark inserted by Windows Notepad. The file should be re-saved in UTF-8 without BOM using Notepad++ or other editor.
