The column general_object_type is missing. This row was introduced at db version 1.4. Do you have an backup of 1.3 or earlier? But keep in mind that you will loose all assignments since then. The other option could add the column by hand with
ALTER TABLE zz_uam_accessgroup_to_object
ADD general_object_type VARCHAR(64) NOT NULL AFTER object_id
and run the following queries
UPDATE zz_uam_accessgroup_to_object
SET general_object_type = '_role_'
WHERE object_type = 'role';
UPDATE zz_uam_accessgroup_to_object
SET general_object_type = '_user_'
WHERE object_type = 'user';
UPDATE zz_uam_accessgroup_to_object
SET general_object_type = '_term_'
WHERE object_type = 'term'";
UPDATE zz_uam_accessgroup_to_object
SET general_object_type = '_post_'
WHERE object_type IN ('post', 'page', 'attachment')
