After debug error, I see this:
SELECT *
FROM (oc_t_preference)
SELECT *
FROM (oc_t_user)
WHERE pk_i_id = '19'
SELECT *
FROM (oc_t_user_description)
WHERE fk_i_user_id = '19'
SHOW COLUMNS FROM oc_t_admin where Field = "b_moderator"
SELECT pk_i_id, s_name, s_username, s_password, s_email, s_secret, i_login_fails, dt_login_fail_date, b_moderator, s_moderator_access
FROM (oc_t_admin)
WHERE pk_i_id = 1
SELECT count(*) as total
FROM (oc_t_item_comment c, oc_t_item i)
WHERE c.fk_i_item_id = i.pk_i_id
AND ( c.b_active = 0 OR c.b_enabled = 0 OR c.b_spam = 1 )
SELECT count(*) as total
FROM (oc_t_item i, oc_t_item_stats s)
WHERE i.pk_i_id = s.fk_i_item_id
AND s.i_num_spam > 0 AND i.b_spam = 0
SELECT *
FROM (oc_t_locale)
WHERE b_enabled = 1
ORDER BY s_name ASC
It can be a problem? How can I fix it?
