Submitted version 1.4.3b with the following updates:

1. Corrected a PHP warning that appears if there are no visits tracked for the date being reviewed.
2. Corrected an issue that had the possibility of generating an error log: If a product's description included a character that would be translated by use of an escape character as part of a SQL command, (eg: he's would be changed to he\'s) then, if that escape character landed in just the right position, it would end up as the last character in the string prior to a single quote as part of the SQL statement. This would then cause an error in the execution of the SQL statement and an error log to be generated. Resolution was to remove the last character if that last character is a \. This issue has been resolved for: page description, last page URI, and referrer URI.
3. Updated the button display of spiders, such that if option 3 is chosen in system setup that a message appears.
