@IgorG thank you for answer. I saw that it could come from pugin so we have desactivate all plugins. But when we reactivate them one by one. But no bugs appeared. Site went back for the day and crashed again on evening.
Can't it be from a php version ? Or an add on that is done by the plesk...
Hi all,
Plesk has updated automatically to Onyx ... There is a wordpress site on it. It creates error 504. We tried to resolved it but don't know where the bug could comes from. FTP and plesk are accessible.
Plesk Onyx 17.8.11 Update #87 on Debian 9.12 Nginx
I have desactivated nginx...
