Appvault problem: proc_close() error

[cpes]

Can someone help me with this. When I try to install application from Application Vault I get an error:

Warning: Program execution failed, please check Plesk log files for details (proc_close() failed: Empty error message from utility.).

In Plesk log I found this:
usermng: neither PSA_PASSWD nor PSA_CRYPTED_PASSWD environment variables are set. unable to determine user's password

and this:
Fatal error: Call to undefined function: mysql_connect() in /var/www/vhosts/domain.com/vault_scripts/joomla/scripts/db-util.php on line 66

Strange. Any suggestions?

proc_close() error itself does not mean much.

Check the Apache error log for more details:
