Hello, ISPConfig version is 126.96.36.199p5 [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.
