Trouble With Header() Redirect On My Php Page

[sylvest]

I have a web page which under certain conditions forwards to another one using the statement:

 

header($next_page);

 

where $next_page == "Location: http://www.sylvesterbradley.org/swchoir/index.php?v=1493894983"

 

This causes a 500 error.

 

I am reasonably sure that I have sent no output at all (other than to a log file) before the header statement. In any case, on other occasions where I have done this I seem to get a warning, which in this case is not happening.

 

I see nothing in any error_log files that I am aware of (that is /home/sylvest/error_log and /home/sylvest/pubic_html/swchoir/error_log) nor do I see anything relevant in the cPanel Errors list.

 

What am I doing wrong? How can I debug what is happening? I have a log statement early in the redirected-to file (index.php) and this does not seem to be being triggered, so I don't think it is ever executing this file.

 

Thanks - Rowan

Most times when I see a 500 error it's usually a page that was supposed to be ASCII was uploaded in binary mode or it has the wrong permissions.
