I decided today to move my blog from WordPress.com to WordPress.org, hosted by Bluehost. The WordPress installation went fine and the export from my blog also had no issues. I installed the import tool and immediately ran into an issue with the size of my import file. It's around 20Mb, so I changed the maxsize setting in the php file and the error didn't show anymore.
After a while though it seemed the import had stopped and when checking the available posts there are none. When I look into the library it seems some pictures have been downloaded, but the format is not like the original (they are almost all square). I tried redoing the import, but I then get the message that a lot of files are already present.
How can I solve this? Select a reinstall from the WordPress menu and try again or do I need to do this differently?
