Greetings, I hope someone can advise me here. I've seen a few threads on this general subject, but none that seem to apply to these circumstances. Since upgrading Plesk, webmail has not worked. Domains forward from webmail.domain.com to webmail.domain.com/horde but then I get a "The Page Cannot be Displayed" error. Webmail is enabled in Plesk and worked perfectly before the upgrade. Can anyone advise? Has webmail been changed in some way which requires other updates to be made to the server, before it will work - compared with 7.1.x? Thanks.
