ECWID plugin: WordPress function wp_remote_post() failed to connect a remote server

cercando di accedere al pannello del mio negozio, tramite l'amministrazione di wordpress, ricevo questo messaggio:

Sorry, there is a problem. This page is supposed to display your store control panel. But this WordPress site doesn't seem to be able to connect to the Ecwid server, that's why there is no dashboard. This is caused by your server misconfiguration and can be fixed by your hosting provider.

Here is a more techy description of the problem, please send it to your hosting provider: "The WordPress function wp_remote_post() failed to connect a remote server because of some error. Seems like HTTP POST requests are disabled on this server".

Please also feel free to contact us at wordpress@ecwid.com and we will help you handle it with your hosting.

qualcuno può aiutarmi?

Hai sbloccato le connessioni server to server?
