Problems with sending queue (one message at a time...)

I am new to PHPList.

I’ve been working on all the configurations, and it seems to be all good now.
I just have one problem, which I don’t understand and can’t solve.

When I try to send a message, the moment I act on ELABORATE THE QUEUE, the send process is immediately activated, but it seems to send ONLY ONE MESSAGE AT A TIME.
The window signals to leave it open, waiting for all messages to be sent…
But it doesn’t seem to do anything anymore.

If after a few minutes you try to unblock sending, then manually force queue processing again, there it goes again.
But again only one message at a time.

Maybe I am missing some knowledge.
But it all seems correct to me…

Thanks

@mlanc The problem might be the one described here

The directions you provided were accurate and decisive, thank you.
In my case the language setting is ITALIAN.
But the problem - clearly - was the same.

I modified the admin/connect.php file and now it works even with the Italian language set.

GRAZIE!
