Error import: Not even one column name match with the header data in file. Check your file data.

Error import: Not even one column name match with the header data in file. Check your file data.

Hi,

in the last synchronization it has failed in 4 tables.
The error I get is:

"Not even one column name match with the header data in file. Check your file data."

So far it had worked fine. I have deleted the data table, changed the import settings, etc... nothing has worked.

If I import to a new table it works, but I would have to do all my reports again.

any ideas?
Thanks.
