I have TE installed and working, and it accepts data entered through Joomla, and displays as expected.

I have the "additional contact fields" plugin enabled and they too seem to be working fine.

I then tried to import various versions of a clean CSV file for 30 contacts, and get an error :

An error has occurred.
1054 Unknown column 'Address '
and additional output of the actual CSV file with everything where it is supposed to be.
It appears as if mysql cannot find the column headings as described in your help, but upon checking mysql through phpmyadmin the tables all appear and the CSV columns are named as it should be and the import should work.
If I delete the "address" column in the CSV, the next column becomes the error, and so on.

So I've followed all your documentation as far as I can tell, and I don't have k2 installed at all.

What's happening?
