Issue Problem with service PHP-FPM

[Erwan]

Hello,

We have a problem with PHP-FM on one website.

First, we first worked with a temporary domain (tmp.domain.fr) to build the website. All was ok.
Today, we have change the temporary domain to the product domain... we have a lot of problem.
The website have a plesk error 503 due to "Inconsistency in the Plesk database".

We have made the corrections with : Internal error: /var/www/vhosts/example.com/httpdocs is out of webspace
One "home" and all the "www_root" from users were not good.

But we have still a problem : when we go on the website, we are redirected to the temporary domain.

We have reload PHP-FPM7.1 service and in the log we have :

[18-Oct-2018 16:20:29] NOTICE: using inherited socket fd=9, "/var/www/vhosts/system/tmp.domain.fr/php-fpm.sock"
[18-Oct-2018 16:20:29] NOTICE: using inherited socket fd=9, "/var/www/vhosts/system/tmp.domain.fr/php-fpm.sock"

In the error_log from the website, we have:
AH02454: FCGI: attempt to connect to Unix domain socket /var/www/vhosts/system/product-domain.com/php-fpm.sock (*) failed

Where is this bas information (old path)? How can we change it?

Thanks a lot....
