Unable to access Plesk on a Linux server: Call to a member function getSkinUrl() on null (SkinUrl.php:18)

Symptoms

• When accessing Plesk, the following error message appears in a web-browser:

  PLESK_INFO: ERROR: Call to a member function getSkinUrl() on null (SkinUrl.php:18)

• When running the plesk login command or repairing the Plesk database with the command plesk repair db, the process fails with:

  ERR [panel] Cannot load settings: DB query failed: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'psa.misc' doesn't exist, query was: select param, val from misc

Cause

The Plesk ‘psa’ database is corrupted: The “psa.misc” table is missing.

Resolution

1. Connect to the Plesk server via SSH.

2. Switch to the directory with daily dumps:

   # cd /var/lib/psa/dumps

3. List all available Plesk daily dumps:

   # ls -l mysql.daily*
   -rw——- 1 root root 236253 Feb 3 01:51 mysql.daily.dump.0.gz
   -rw——- 1 root root 229653 Feb 2 01:48 mysql.daily.dump.1.gz
   -rw——- 1 root root 222485 Feb 1 01:56 mysql.daily.dump.2.gz

   • where mysql.daily.dump.0.gz is the most recent daily dump.

4. Restore the ‘psa’ database from the most recent daily dump. In this example, the ‘psa’ database is restored from mysql.daily.dump.0.gz:

   # zcat mysql.daily.dump.0.gz | sed -n ‘/– Current Database: `psa`/,/– Current Database:*/p’ | MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysql -uadmin

5. Open Plesk.
