Forums

Till now I was very happy with Chronoforms using for Joomla. Since I do more and more Sites with Wordpress, I was also very happy to see the plugin for WP. I am not a develeoper and need a Formmail Tool that´s easy to handle.

Now I am getting an Error while a simple redirect.
The redirecr ist the last action on the on submit event.
Checkt it on 2 themes, but both done with "virtual composer"
I checkt a lot of posibilities. Field Names, Did it on a second Projekt...nothing helps.

This is the Alert:

Warning: Cannot modify header information - headers already sent by (output started at /kunden/90564_30926/webseiten/DOMAINXXX/wordpress/north/wp-includes/nav-menu-template.php:454) in /kunden/90564_30926/webseiten/DOMAINXXX/wordpress/north/wp-content/plugins/chronoforms/cegcore/libs/env.php on line 6

it must have something to do with this function:

public static function redirect($url){
header('Location: '.str_replace('&', '&', $url));
ob_end_flush();
exit();

but I am not good enough to check this.
Am I the only one who got this problems on two WP Project?

nice weekend

Hi ceewee,

No immediate suggestions; please post a link to the form so I can take a quick look.

Bob

Here is the Form:

thanx

Hi ceewee,

Please will you open the file wordpress/north/wp-content/plugins/chronoforms/cegcore/libs/env.php and copy the first dozen lines here. Line 6 is a comment in the version I have here.

Bob

OK, Line 6 was because I deleted the Comments, as I was looking for Spaces the force such Errors.
I replaced it now with the original one und now the Error ist again on line 15

Hi ceewee,

That explains the line numbers thank you.

I don't see quite where the error is :-(

You might try using the WP redirect method in a Custom Code action instead of the ReDirect action.

Bob

Im not sure if this is correct:

<?php wp_redirect( 'http://spitze-n-kraft.de/danke-fuer-ihre-anfrage', 301 ); exit; ?>

getting now:

Warning: Cannot modify header information - headers already sent by (output started at /kunden/90564_30926/webseiten/spitzenkraft/wordpress/north/wp-includes/nav-menu-template.php:454) in /kunden/90564_30926/webseiten/spitzenkraft/wordpress/north/wp-includes/pluggable.php on line 1228

Meanwhile I checked a third Projekt. There I build only 3 Forms with Chronoforms on the default Theme of WP.
I only used the "Display Message". Now i testet a redirect and get the same Error.
It looks like the reason for that hase to be found at the Chronoform-plugin and not at WP.
😟

Hi ceewee,

I don't know - the first error doesn't look as though it is from ChronoForms, the redirect one might be.

I don't' remember seeing this particular error reported here before. I know that there have been some conflicts with other WP Plug-ins.I'll try to run a test on a WP Installation when I can.

Bob

I found out, that in the mainproject "spitze-n-kraft" the plugin
"ubermenu 3" causes the error.
If deaktivated no error!
But I need the plugin, because the coders for the theme deliver a menu that is not working on Android Smartphones...

I installt the latest update from the Theme and from the ubermenu....no changes...

I´m getting sad....not enough time for those things...:-(

HI ceewee,

I suggest that you try the UberMenu support - it may be just that there is a space output somewhere. Or they may be able to pin down why there is a problem with the ChronoForms & WordPress redirect codes.

You can also ask Max, the owner and developer here, using the Contact Us menu above and linking to this thread - it's just possible that he has seen this before.

Bob

I contacted the ubermenu support,
but I don´t think that the can help.
As I said, I testet it on a WP Installation without plugins and with the default WP theme and the same error occurred.

Hi ceewee,

Please check with Max as I suggested, he may have some suggestions.

Bob

Hi,

I get the same error with the redirect action here, but you said that you could solve it by disabling some plugin, however, when I search on Google "Warning: Cannot modify header information - headers already sent by", I find lots of similar reported errors coming from different WordPress files, so I don't think this issue can be solved easily.

You may however use this workaround:
