Suddenly I got 2049 visitors and 2042 of them was a bad one. All 2042 had the same information. As I can see in the program file hits.class.php the visitor shall only be INSERTed to the table ones a day.
Shouldn’t it be better to append a counter, as for excluded visitors, and try with an UPDATE of the counter before an INSERT is executed?
But I’m still confused about why the visitor was appended so many times. I know that the visitor was a hacker trying to login. I have a back up of the sql-table.
