I'm having trouble exporting my wordpress blog contents to move from one host to another, both are running v2.2.
The export function seems a-ok and generates an xml file which is around 700k. It appears to only contain about half the posts & comments in the original blog, cutting off around January 2007. Opening the file in IE or an XML validator fails, so there's some bad chars etc in there, but in the end the original file simply doesn't contain all the posts. The content just stops, the file doesn't even close tags properly.
I've checked the server logs and can only see 200 codes when I run the export, so I assume wordpress also thinks everything is just fine.
Is there something else obvious I should try? My next step is to tackle at the mySQL level, which I'd prefer to avoid if I'm able.
