Firstly, this is an excellent (and powerful) import module capable for importing large volumes of data in book pages, etc and a brief thank you for your work on this. Thought I should report that after using this module with a specific user on the 7/8 attempt the module fails and there's no apparent reason for it. The module fails to automatically recognise the format of the import (e.g. .csv) and then throws up error messages. In short, it no longer works.
If however, I switch to another user, with the exact same file, it works fine; but again fails after repeated use (so I go to another user and use this one instead). Not a real issue for me/us as we will only be doing bulk imports on an ad hoc basis.
Just thought I'd let you know ;-)
