Publishing error

[pfgreig]

Folks...for weeks all has been ok, I have been away for a few days and no changes have been made yet suddenly I am unable to publish...I have checked for similar issues on this forum but cannot find any.
When I attempt to publish I get a long list which might as well have been written in Swahili...(see below) can anyone suggest what I might do to correct it?
Thanks
Paul.

[jerryco]

Did you try using SFTP if you didn't already use that?

[Pablo]

Usually, when publishing suddenly stops working there is an issue with the server.
Or else maybe a recent update of your firewall block the connection?

[pfgreig]

Thanks all...I have tried what you suggest, to no avail. As said I have changed nothing??

[jerryco]

Did you ask your host if they changed anything?

[Bluesman]

In "Edit" Publish location... have you the "Use passive mode for transfers" checked?

[pfgreig]

Thanks all, I am currently awaiting response from my host in regards to any changes at their end, and yes, 'Use Passive Mode for Transfers' is checked.
