justsomeguy Posted August 17, 2011 Share Posted August 17, 2011 It says there is output on line 1. If you don't have any spaces or anything else before the opening PHP tag, then it might be a UTF issue. Try to save the file as a UTF file without the BOM option.

justsomeguy Posted August 19, 2011 Share Posted August 19, 2011 You have the code on top of the processing page checking if the captcha is valid or not. You can add your code there to insert a new record into the database. Link to comment Share on other sites More sharing options...
