Cause

PHP 5.4.45 was installed from a non-default repository, while dependent packages were installed from the default (Centos-Base) repository. PHP 5.4 version that comes from default repository is 5.4.16.

Resolution

Remove PHP 5.4 if it is not required

If PHP 5.4 is not required, remove PHP 5.4 via Plesk installer.

Note: If some domains are using this PHP version, change PHP version to any other:

- - per domain
  - for several domains

Reinstall PHP 5.4 if it is required

Connect to the Plesk server via SSH.
Reinstall PHP 5.4 via Plesk Installer:

2.1. Uninstall PHP 5.4:

# plesk installer --select-release-current --remove-component phpgroup

2.2. Install it back:

# plesk installer --select-release-current --install-component phpgroup
Rerun Plesk Update.
