We've been running a Mantis 1.1.8 install for some time. Recently, we had a need to export a project. As such, I upgraded to 1.2.5 following the instructions here: http://www.mantisbt.org/manual/manual.installation.upgrading.php
Now, I'm trying to export the project as XML from the View Issues page. I've got about 100 issues to export (for this test), and Export XML is returning a blank XML document. Exporting as a CSV is working fine. Any ideas why this is?
I've tried a number of different variants, with no success.
