Curious. Did you happen to submit the SQL patches more than once?
You can execute the following SQL to uninstall/reinstall the SQL, to make sure everything is inserted properly and get rid of duplicates:
Code:
DELETE FROM xcart_modules WHERE module_name='XC_SEO';
DELETE FROM xcart_config WHERE name='xcseo_keyword_injection';
DELETE FROM xcart_languages WHERE name IN ('module_descr_XC_SEO','module_name_XC_SEO','option_title_XC_SEO','opt_xcseo_keyword_injection');
INSERT INTO xcart_modules (module_name, module_descr, active) VALUES ('XC_SEO','This module rewrites your website urls for Search Engine optimization.','Y');
INSERT INTO xcart_config (name,comment,value,category,orderby,type,defvalue) VALUES ('xcseo_keyword_injection','Specify a keyword to inject into rewritten urls','','XC_SEO',10,'text','');
INSERT INTO xcart_languages (code,name,value,topic) VALUES ('US','module_descr_XC_SEO','This module rewrites your website urls for Search Engine optimization.','Modules');
INSERT INTO xcart_languages (code,name,value,topic) VALUES ('US','module_name_XC_SEO','XC SEO','Modules');
INSERT INTO xcart_languages (code,name,value,topic) VALUES ('US','option_title_XC_SEO','XC SEO options','Options');
INSERT INTO xcart_languages (code,name,value,topic) VALUES ('US','opt_xcseo_keyword_injection','Specify a keyword to inject into rewritten urls','Options');
