  • Plesk 11.5 for Linux


The following error is shown in Parallels Plesk when attempting to set an IP address that is not registered in Plesk's IP Adresses menu for any A record on a domain:

PHP Catchable Fatal Error: Object of class Ip_Address could not be converted to string
Line: 1054
File: /usr/local/psa/admin/plib/Dns/Manager/Common.php
Stack Trace:
#0  Smb_Exception_Syntax::handleError(4096, Object of class Ip_Address could not be converted to string, /usr/local/psa/admin/plib/Dns/Manager/Common.php, 1054
#13 DNSSyncUIPointer->accessItem(GET, ) called at [/usr/local/psa/admin/plib/UIPointer.php:619]
#14 UIPointer->access(GET) called at [/usr/local/psa/admin/htdocs/plesk.php:36]


Such behavior is considered a software issue and is planed to be fixed in future releases. The internal ID regarding the matter is PPPM-1879.


The issue is caused by excessive entries in Plesk database related to domain aliases. In order to work around the issue, domain aliases should be re-created on the domain that is affected. You may use the attached script to automate the process:

cd /root
chmod +x ./;sed -i 's/\r//' ./

Please replace with the actual domain name.
