It occurred after I entered in a value in admin --> config --> time zone offset.
What value did you enter???
It looks like you might have entered "13"
Code:
13 HOUR), '0', 'login.php ', '', '76.25.247.55')' at line 1
Where the allowable values defined by
Code:
Enter +h, 0 or -h where ''h'' is the number of hours.
would be maxed at +12 or -12 and a 13 would probably cause a math error
If you use phpmyadmin and edit the configuration table or export it edit and re-insert/import it
look for 'TIME_ZONE_OFFSET'
Always backup before making any DB alterations....
