I'm trying to migrate our organization from a server running Openfire 3.7.0 beta to a server running Openfire 4.0.3. The old server is running version 2.2.1 of the User Import Export plugin, and the new server is running version 2.6.0.
The user exports from the old server seem to be fine, but the import process is hitting a snag. Upon selecting the XML file to import and clicking the Import button, I'm taken to an Openfire page with an empty body (see attached). No errors are shown, and none of the log files appear to be modified.
I'm able to successfully export from the new server, but I encounter the same blank page problem when I turn around to import these files back into the new server. Interestingly, I also get the blank page when hitting the Import button without selecting a file at all.
