There are {0} or more empty lines in your sent file, please correct this
Explanation:
The import file contains more than 10 000 empty lines between the article lines. If the number of empty lines becomes too great, this message will appear.
Solution:
Remove the empty lines from the import file. Do this by selecting everything and then filtering by article number. It may be that (as in the example) after a large number of empty lines there are still some article lines.
Wrong: After a great number of empty lines, there is an article present, as shown in the row numbers when filtering away the empty lines.
