Apply this "If!!! only if" you have this error:

#1062 - Duplicate entry '80' for key 'PRIMARY'
....

On questions that are asked to me this error is seem.id has been used as 80(id=80) that is the reason of it.
It means there is an other contribution that uses id 80.
If you have an error like that use the sql query down below.

insert into configuration (configuration_id, configuration_title, configuration_key, configuration_value, configuration_description, configuration_group_id, sort_order, last_modified, date_added, use_function, set_function) values ('888', 'RSS Articles', 'MAX_RSS_ARTICLES', '20', 'Number of articles displayed by the RSS feed', '3', '25', 'now()', 'now()', NULL, NULL);
ALTER TABLE products ADD products_to_rss TINYINT default '1' NOT NULL;
