That usually suggests there is some white space somewhere or that something has been echoed to the page before a segment of PHP code is executed, but I can't see it on the files you have sent over. Is the file standalone or part of any other framework / includes?
you mean is it part of a template page, if so yes. But basically I have 2 things at work here:
An attempt to set up a dealer/user login and registration with security and an attempt to search orders by dealer id and password. The log in security is not yet applied to the search orders/update yet, because that is not working either. I had it partially working, went back to scratch and started over, but now it isn't finding orders at all.
