I'm having problems importing a WordPress eXtended RSS (WXR) file from one installation of WP to another. Both are ver. 3.x.
The error message I receive is as follows:
Please upload a valid WXR (WordPress eXtended RSS) export file.
The file in question was exported from a remote hosted WP blog, that I no longer have access to, and I wish to transfer everything to my WordPress.com site
Weirdly if I attempt to import to a locally hosted 3.x version of WP, the operation proceeds without a hitch. The problem exists only at WordPress.com.
Any ideas? Thanks in advance.
