I thought I'd ask before hacking the config file.... </p> https://www.machform.com/forums/topic/error-cannot-modify-header-information#post-1907 Wed, 28 May 2008 10:24:11 +0000 yuniar 1907@https://www.machform.com/forums/ <p>Hmm... you are right. It shouldn't send any header when using advanced code.</p> <p>Don't remove the header line in your config.php file. Instead, add a '@' character in front of it. So it become like this:</p> <p><code>@header(&quot;Content-Type: text/html; charset=UTF-8&quot;);</code><br /> <code></code> </p> https://www.machform.com/forums/topic/error-cannot-modify-header-information#post-1901 Tue, 27 May 2008 18:05:04 +0000 jonathanryan 1901@https://www.machform.com/forums/ <p>I've just plugged a form into a Wordpress page using the "advanced" installation. The iFrame version works fine but I hate iFrames....</p> <p>I get the following error</p> <p>Warning: Cannot modify header information - headers already sent by (output started at [webroot]/wp-content/plugins/all-in-one-seo-pack/all_in_one_seo_pack.php:158) in [webroot]/machform/config.php on line 51</p> <p>(The [webroot] bit is actually the full path to my code - I edited the message for display here). Then the form loads properly. It's a warning rather than an error but looks a bit messy.</p> <p>I took a look at the error line in config.php and it looks like it's just setting the page to UTF-8. Is there a good reason for this? Can I just remove it from config on the grounds that all my pages will include it or will it choke when I try to test forms standalone? </p>
