Resolved After todays update ERROR: Zend_Db_Adapter_Exception: SQLSTATE[HY000] [2002]

[CoyoteKG]

Hello,
I just updated last 8 things, and it looks like it was updated successfully,


Sites works, but in the top of the page I got this error.
Do I need to be concerned? Because on few posts I see that users have problem to log in Plesk, and boot to OS after simillar error.

Internal error ;-P

It looks like the typical message during an update of MySQL or MariaDB libraries. The reason for it is that during the update the service must be stopped and files are removed. After the update the service is restarted and things will be o.k. again. Zend Adapter recognizes this and shows the message, but only for a short time. If the message does not persist (does not stay on the screen but has disappeared) everything is o.k. You only need to worry if the messages stays on the screen, but in that case Plesk should not be usable anyway, because then the database would be inaccessible, hence a login impossible.

Hi Peter,

I refreshed page, and there is no that message.
It looks like everything is OK.

Thx
