Hello I'm trying to import Categories on my tiki web site
and always get the message below
Seems the file you were importing has a BOM "header" in it, which the code wasn't handling properly. So for now resave the file as UTF-8 without BOM and all should work as expected.
I have fixed this in Tiki 22.x now so if you can update easily that it should work ok now with your existing files. If it's a good fix then i'll backport it to 21.x too.
