18.0.62

Hello,

I have a problem with Plesk. Suddenly It doesn't work anymore and I got a error message 404 nginx. I tried plesk repair ASPECT -n.I got the message: plesk: command not found. I found this article in web for solution: (Plesk and its command-line utillities do not work du missing Plesk packages) Plesk and its command-line utilities do not work due to missing Plesk packages - Support Cases from Plesk Knowledge Base. I used ./plesk-installer and got a failure message during installation.
