Just to report another Posterous import problem in the last few days in case it is related - using Firefox 20 on Mac 10.5.7 (Lion).
My import of the XML file worked partially. It was a very small blog. Not all text imported and only one of the four images on the blog.
I do not know whether the problem was with the XML exported or a problem with the import process.
As it is just a small blog, I copied and pasted to rebuild it on WordPress.com and did not bother to report it as a problem.
I have exported blogs from Posterous and then imported to WordPress.com with lots of posts and images in the past with no problems.
A bit of a heads up:
- look at your WordPress.com content in "text" view for any posts or pages that have media embedded, to check that the media have actually been imported.
- Media that are unsupported in WordPress.com, like audio and video, might appear to have been "imported" but they will just be in links to media that is still embedded back on Posterous - so will fail when Posterous closes at the end of the month. (My audio files disappeared off Posterous a long time ago and I had to upload them elsewhere and re-link to them on my free WordPress.com sites).
- pdf files are embedded on Posterous via Scibd. I replaced all these embeds as I wondered if they might disappear too, even if they are still saved somewhere on Scribd.
Hope this is helpful,
