It seems that it is a bug of this version v1.15.4. There is indeed an error in the DB.
DB Error #1054
[SELECT A1.id
, A1.name
, A6.address
FROM ost_user
A1 LEFT JOIN ost_user_email
A2 ON (A1.id
= A2.user_id
) LEFT JOIN ost_organization
A3 ON (A1.org_id
= A3.id
) LEFT JOIN ost_user_account
A4 ON (A1.id
= A4.user_id
) LEFT JOIN ost_user__cdata
A5 ON (A1.id
= A5.user_id
) LEFT JOIN ost_user_email
A6 ON (A1.default_email_id
= A6.id
) WHERE (A2.address
LIKE '%yael%' OR A1.name
LIKE '%yael%' OR A3.name
LIKE '%yael%' OR A4.username
LIKE '%yael%' OR A5.phone
LIKE '%yael%') LIMIT 25] Unknown column 'A5.phone' in 'where clause
I have solved it with an answer found in this great Forum.
