Plesk interface displays the following error:

    ERROR: Call to a member function sdkInstanceLimits() on a non-object (Limits.php:44)


The issue is caused by the failed Plesk upgrade. Example, such situation may take a place when Pleks database is upgraded, but Plesk packages not.


  1. Check Plesk database version:

    # MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysql -u admin psa -e"select * from misc where param='version'"
    | param   | val       |
    | version | 012000018 |
  2. Check Plesk packages versions, example:

    # rpm -qa |grep plesk

From output above Plesk packages have version 11.5, but Plesk database is 12.0. So in this case it is necessary to roll back Plesk installation to a pre-upgrade state, resolve the issue that caused the upgrade failure, and re-run the upgrade. Use the following article to perform the required actions.
