ISPmanager: Troubleshooting

This is documentation for an outdated product. See the current documentation


Web module


After updating PhpPgAdmin on Debian users cannot log in to the control panel. The panel displays the following error messages

PhpPgAdmin by default displays all errors. Updates delete all the changes made by the control panel. To resolve the issue, change the following line in the configuration file /usr/share/phppgadmin/libraries/





Cannot login with the password generated in ISPmanager

Perhaps, you run Mysql 5.7. Due to the changes in this version you can log in as root only by connecting from the process which runs with permissions of the system root user.

To log into phpmyadmin enter user credentials of a certain database.

WWW domains are missing in the control panel

If a menu section is missing in ISPmanager, this means that the module is not uploaded. E.g. in ISPmanager the "WWW domains" module is not displayed, and the log file contains the following record:

WARNING Module 'webdomain' was unloaded

Possible reasons:

  • apachectl -M failes
  • The WebModules, WebGroup, WebUser directives are missing in the ispmgr.conf configuration file.
  • Configuration files of web-servers are missing in /usr/local/mgr5/etc/ispmgr.conf.d/.

IP address management

Cannot add the IP address to the server interface from the "IP address" section.

Error:  Cannot assign the IPv4 address. The cluster node 'node1 (' cannot manage IPv4 addresses
The log file contains the following information : ERROR Error: Type: 'ipmanage' Object: 'ipv4' Value: 'node1 ('

When adding an IP address from a new subnet, you need to add the address from the subnet to the server network interface. This error means that there are no IP addresses from the network and you need to add one address manually.

The DefaultInterface directive in the ispmgr.conf configuration file (ISPmanager LIte) or ispmgrnode.conf (ISPmanager Business) defines the network interface where ISPmanager will search for the IP address.

Example: DefaultInterface bond0

Restart the control panel to apply the changes

killall core

Cannot start the control panel

Cannot start the control panel. When trying to start the panel from the console, we can see

#cd /usr/local/mgr5/
#bin/core ispmgr
terminate called after throwing an instance of 'mgr_err::Error'
 what():  Type: 'crypto' Object: 'decode' Value: 'error:0906D066:PEM routines:PEM_read_bio:bad end line'
Abnormal end 

Possible cause of this error is an invalid SSL certificate. Delete all the certificate files from the directory /var/www/httpd-cert/ and start the panel

mv /var/www/httpd-cert/* /root/

WordPress and SSL

ISPmanager doesn't configure Nginx for WordPress. You need to configure WordPress to avoid redirects. Set up the plug-in in WP "ssl-insecure-content-fixer" and select "HTTP_X_FORWARDED_PROTO" in the WP configuration form.
