Issue More access to databases (broken link)

[Christophe56]

Hello,
I had a crash with my Plesk 12.5, definitely due to the latest update!
I would like a little help please!

The mysql service did not start on the machine.http://imgur.com/a/VMlwA

I tested a Plesk repair with the command:

plesk installer --select-release-current --reinstall-patch --install-component panel

I had errors:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
failed
***** problem report *****
ERROR while trying to establish test connection
Check the error reason(see log file: /dev/stderr), fix and try again

I opened the log: /var/log/mysqld.log

I did not find a solution, so I reinstalled Mysql (version 5.6) and I restored the last backup of Plesk [13/03]!

I have access to my Plesk again, but my websites can not find their database!
The databases on Internet sites appear correctly in Plesk, when I enter one of the databases, the tables appear, but when I try to access, error # 1146 indicates that the table does not exist.
I think I have a link problem between the existing databases and Plesk.

Would you have an idea to deal with that?

I do not want to reinstall everything!

I have tested several commands to repair the tables, but it does not work.
I looked in the mysqld.log file
Here are some of the recurring errors displayed:
