I have a plain-jane blog using WordPress 3 with a slightly modified default theme.
I wantto use Disqus on my blog but have been unable to import my comments into Disqus. The auto importer in the Disqus plugin does does not work ans manual imports fail too. I am trying to import about 6,000 comments.
I have contacted Disqus support. They were prompt in the beginning but now it is as if I don't exist. Their final email to me was:
When looking at your most recent import for example the file itself doesn't have a proper ending; it just ends in the middle of a comment's XML data. Here's a screenshot for reference: http://dl.dropbox.com/u/15229959/Screenshots/0~h.png
Most likely this is due to WordPress setting a limit on how big the file can be before being cut off during the export process. One possible method to remedy this would be to export one month at a time (or a few months at a time if you can get away with it). Try exporting in that fashion and let us know what you find or if we can help with anything further.
Any suggestions? I told them I couldn't find a way to import the comments one month at a time.
