Confluence doesn't import ZIP file and logs error

Exported a space from Atlassian (self-hosted) v6.1.2, copied the zip file to the file system on our confluence server (self-hosted 6.1.3). Selected import, pressed "Import" and it eventually returned to the Pages view with nothing imported.

The atlassian log records a massive call-stack (I removed the middle 100 odd lines!) incuding:

From the URL in the stack trace:

/spaces/doimportpages.action

and your description of the import process, it sounds like you were importing the space via the Space Tools>Content Tools menu. That option is for importing text files. The text files become pages in Confluence.

Please try importing the space from the Confluence Administration>Backup and Restore menu (<Base_URL>/admin/backup.action).

I look forward to hearing how it goes.

Thanks for that. It worked perfectly. It would be nice if the Content Tools either specified that, gave a link etc. because it is not clear why it wouldn't work like the Atlassian article I found about restoring spaces said i.e. that you can only do pages in that menu, especially since the selected file was a zip, which gives a clue ;-)

Thanks again.
