Hi,
If you have a premier subscription, you should post in the Premier Forum where the questions are often answered by the developer.
premier is now 4.6.3
Your CSV file is not in the correct format. Request is not a correct header. from the documentation:
“The header MUST match the list of field names below.
Base Field Names
These are the fields provided by Store Locator Plus that can be imported by the CSV file. The header field names should be entered exactly as listed. Items with two options can use either option, the faster processing option is listed first……….”
etc
#See the various documentation pages about CSV file, imports exports etc.
