Web URL error, please double check

double check on what?

Most probably the server closed and extension no longer works, see


I am facing the same problem too. Did you manage to find a solution?

The example you are using is a php server solution…
which means, if the server which will be used to send the mail will go down, all apps, which use this extension will not work anymore…
