Fix error Headers already sent - general php

[attom1]

Hello,

 

Account history page in 2.3v has error:

Cannot modify header information - headers already sent by (output started at /home/patosira/public_html/includes/languages/english/account_edit.php:72) in /home/patosira/public_html/includes/functions/general.php on line 49

 

Code present on line 49:

 

header('Location: ' . $url);

 

Thank you kindly

The place to fix is includes/languages/english/account_edit.php, line 72. On my copy, that's the very last line of the file ?> and it's very likely you have some spaces (blanks) after the ?>. Remove those spaces or blanks.

 

Did you edit this file? If so, you or your editor added some crap after the closing ?>.

Thanks for your reply. Yes mine is blank space too. Haven't done any changes to account edit.

?> line 71

Line 72 (empty)

Will try

Had a quick go deleting empty line 70 and appears no change. Will have a fiddle around later when back working! Thanks

You want to delete every single character and line after the closing ?>. What comes before it doesn't matter. Usually blank lines after will cause a 500 error, but not always. Blanks or other characters on the same line (after ?> ) will definitely cause the "headers" error.

 

What's happening is that anything in a .php file not between <?php and ?> is considered straight HTML, and is sent directly to the browser as HTML. So, a blank after ?> will be sent as a piece of text to be displayed. When the first piece of text is sent to the browser, all "headers" are first flushed to the browser. If you've sent a piece of text too early, and then the program (PHP) tries to set more "headers", that will generate the error.
