Earlier I had another issue, which is making the first row the column names. Even though I ticked the checkbox which function is for that, while it did set the column names, it still used the first row as the part of the data too. So the first row of the created table contains the names. But after I downloaded a newer version of xampp, it doesn't happen again, but the drag and drop failure is still happening.
Why is that?
Here is the screenshot of the error.
