[Solved] ispconfig3_roundcube + soap error: looks like we got no xml document

Hello,
ISPConfig version is 3.0.5.4p5
[INFO] php (cli) version is 5.6.5-1
Debian version: Linux xxx 3.10.23-xxxx-std-ipv6-64 #1 SMP Tue Mar 18 14:48:24 CET 2014 x86_64 GNU/Linux
Roundcube Webmail 1.0.5 (Up to date)
ispconfig3_roundcube (Up to date)

remote user created, all Functions activated (for testing purpose & to be sure it's not an access right problem))

Remote API Allowed:
# grep api /usr/local/ispconfig/security/security_settings.ini
remote_api_allowed=yes

# cat /var/www/xxx/web/plugins/ispconfig3_account/config/config.inc.php
<?php
$rcmail_config['identity_limit'] = false;
$rcmail_config['remote_soap_user'] = 'remote';
$rcmail_config['remote_soap_pass'] = 'xxxxxxx';
$rcmail_config['soap_url'] = 'https://xxxx:yyy/remote/';
?>
(port is not 443)

I first had a problem with remote https access. Problem solved by installing a SSL certificate Valid (not self signed).
Now this XML error. I searched the forum and Internet abour this error without success

I tried this: https://www.howtoforge.com/community/threads/soap-error-looks-like-we-got-no-xml-document.62307/
Without success (it's not for my Ispconfig version)

I found nothing usefull in Apache2 or roundcube logs...
I am out of ideas (except downgrade roundcube to 1.0.4, but I don't tried yet) so I asked for help today.

Thank you in advance for your help.
Laurent.

 

Hello Till,
Thank you for your answer.

"Unfortunately" it works very well: Blank page without error. The remote connexion is good.

I'm trying to debug the soap answer in inserting the code bellow in the php files:
'wsdl_cache' => 0,
'trace' => 1
and
echo $client->__getLastResponse();

But I'm not able to use it corectly... /-)

 

Hello,
I walk a little on the debug...
In file ispconfig3_account.php
Error is showed by line 179, so I replace it with something more usefull for me:

// $this->rcmail_inst->output->command('display_message', 'Soap Error: ' . $e->getMessage(), 'error')
$ses_er = print_r($this->rcmail_inst->config->get('remote_soap_user'), true);
$this->rcmail_inst->output->command('display_message', 'Soap Error: ligne 179 ' . $e->getMessage() . " - " . $ses_er, 'error');

I get now (of course...): Soap Error: ligne 179 looks like we got no XML document - remote

I'm trting now to play with function init() - Line 9 to 20
With this:
function init()
// {
// $this->rcmail_inst = rcmail::get_instance();
// $this->load_config();
// $this->add_texts('localization/', true);
// $this->soap = new SoapClient(null, array('location' => $this->rcmail_inst->config->get('soap_url') . 'index.php',
// 'uri' => $this->rcmail_inst->config->get('soap_url')));
// $this->register_action('plugin.ispconfig3_account', array($this, 'init_html'));
// $this->register_action('plugin.ispconfig3_account.show', array($this, 'init_html'));
// $this->add_hook('template_object_identityform', array($this, 'template_object_identityform'));
// $this->include_script('account.js');
// }
{
$this->rcmail_inst = rcmail::get_instance();
$this->load_config();
$this->add_texts('localization/', true);
$this->soap = new SoapClient(null, array('location' => $this->rcmail_inst->config->get('soap_url') . 'index.php',
'uri' => $this->rcmail_inst->config->get('soap_url'),
'proxy_host' => 'xxxxxxxxx.xxx',
'proxy_port' => yyyyy

));
$this->register_action('plugin.ispconfig3_account', array($this, 'init_html'));
$this->register_action('plugin.ispconfig3_account.show', array($this, 'init_html'));
$this->add_hook('template_object_identityform', array($this, 'template_object_identityform'));
$this->include_script('account.js');
}

I get
Soap Error: ligne 179 Could not connect to host - remote

I do not despair of understanding what's going on ...
If anyone sees a better way to debug, he does not hesitate to let me know!
If I can find the problem, I would not fail to share the way I get around.

Laurent.

 

Hello,
I have not given up (although I've left a little while)!

I created an Apache2 session for ISPConfig listening on 127.0.0.1:8080 without ssl to avoid potential problems with https.

I still have the same problem, and something "funny" ... I have exactly the same problem with another module (Ispconfig for Whmcs): https: //github.com/cwispy/ispcfg3

Module Command Error
SOAP Error: Looks like we got no XML document

This could be a problem with ISPConfig since the same error is reproduced with two different modules.

Interesting information: I have no error with the tab change password ISPConfig module for Roundcube.

 

Strange and annoying problem ... I do not think it's a problem with the version of Roundcube or even with the modules.

Apache or php perhaps?
I continue to look for a way to get a workaround.

Thank you Till for bother to answer me.

 

Nope, no mod-security nor mod-security2 installed.
I found this lines in apache error logs:

This is obviously related to my problem!
Finally, an early commencement of research approach...

 

"Unfortunately" no, I have already check.
I tried with "fresh" files from my /tmp ispconfig archive, and I also tried to convert files with "dos2unix" command.
Files are Ok, no space at beginning or "dos" characters inside.

Contrary to what I thought it was not related to SOAP (it seems).

I keep trying to understand what's wrong...
I will not repeat it in every post, but still ... thank you Till for your interest and support!

 

F**k! Got it.

always_populate_raw_post_data = -1

The Apache log was the track to follow!

Perhaps it is linked to my apache ou PHP version (Are they fully compatible with Ispconfig ?)
# apt-cache policy apache2
apache2:
Installé : 2.4.10-9
# apt-cache policy php5
php5:
Installé : 5.6.5+dfsg-2

But it is solved, no more SOAP error and no more apache2 error logs! Phew ...

 

In all my php.ini (apache2/cgi & cli) it was commented (and not by me).
;always_populate_raw_post_data = -1

It's perhaps a new default presset on Jessie ?
I don't remember how it was on Lennie or Wheezy.

 

Hi Till,
I confirm the problem on another server. I do not have, either, activated manually the option on that server.

Defaults settings of php.ini
; Always populate the $ HTTP_RAW_POST_DATA variable. PHP's default behavior is
; to disable this feature.
; http://php.net/always-populate-raw-post-data
; always_populate_raw_post_data = On

Modification to do:
; Always populate the $ HTTP_RAW_POST_DATA variable. PHP's default behavior is
; to disable this feature.
; http://php.net/always-populate-raw-post-data
; always_populate_raw_post_data = On
always_populate_raw_post_data = -1

By modifying the php.ini (which I had not modified before) the error disappears.

apt-cache policy php5
php5:
Installé : 5.6.6+dfsg-2

What I found strange is the comment in the php.ini...
"PHP's default behavior is to disable this feature"

Best Regards,
Laurent.
