Did you unblock the server to server connections? You can do it from the AlterVista control panel: go to the Resources section, then click on Edit PHP Settings. In that page you can find the instructions to follow.

I have the same problem

Every installed application on your webspace can establish http connections to the outside by using php function fsockopen() or cURL libraries.

Warning: for security reasons and to prevent potential service abuses, every server to server connection is subjected to logging. Furthermore, the ip address of the script executer client and its hosting website will be transmitted and therefore visible to destination server.
The external access is restricted to the domains in whitelist
External access without restrictions

I have External acces without restrictions checked

Please someoine can help me

Did you wait some minutes? The unblock isn't immediate.
If you still read error messages, could you please write the exact steps needed to reproduce the problem?

There's nothing to do, PHP scripts can't use the exec function. You have to use a plugin that optimizes images using an external service.

Do you know one that can i use please?

There's this: https://wordpress.org/plugins/wp-smushit/ but it looks like that the online service it was using is no more available.
There are also plugins like https://wordpress.org/plugins/kraken-image-optimizer/, but you have to pay to use them.
