sampoyigi thank you! that worked but led me to my next speed-bump.
i'm trying to make sure the login fails if a customer's "validated" value is 0.
i added line 84 in /system/tastyigniter/libraries/Customer.php
83: $this->CI->db->where('status', '1');
84: $this->CI->db->where('activated', '1'); // the added line
without the added line it works fine. once added i receive the following error
ERROR - 2019-01-07 04:37:05 --> Query error: Unknown column 'activated' in 'where clause' - Invalid query: SELECT *
WHERE `email` = 'firstname.lastname@example.org'
AND password = SHA1(CONCAT(salt, SHA1(CONCAT(salt, SHA1("gfdsgsgfds")))))
AND `status` = '1'
AND `activated` = '1'
ERROR - 2019-01-07 04:37:05 --> Severity: error --> Exception: Call to a member function num_rows() on boolean /system/tastyigniter/libraries/Customer.php 87
thanks again in advance of any help 🙂
