I'm trying to import some multi-value custom field and I am getting what is clearly a badly formed error message. I've eliminated most of my errors by careful perusal of my import data and correcting a couple of typos. But I can't find the last one.
It gives me a link to an error CSV to export (like normal contact import) but it contains what looks like code to me. This is what it gives me in 2x6 cells of the CSV. There is also a bit of html showing as text (line break and "warning" in bold, but I can't workout how to show these in SE)
Warning: Declaration of CRM_Custom_Import_Parser::run($fileName $separator &$mapper $skipColumnHeader = false
What does this mean???
Note that the documentation calls it multi-value, but the tag I have found is multi-record which describes it better.
