I'm having a similar problem to one posted earlier this month. It takes hours to publish or regenerate the site. I'm hosted by Hostcentric, version 8.3 and have had an open ticket with them since Feb 29th. I'm about to move my site which will be a huge effort. Today they restored my database using an old backup which put my site into a major mess and I can't even fix it.
They keep promising me it will be fixed shortly and nothing happens.
Does anyone have any suggestions at all???????
Thanks!
