i18n_register error

Hi, I try to drilldown from table cell to specific html page which saved in my Splunk server. When the page is loaded, I can see there are errors for each one of my JS files: Uncaught ReferenceError: i18n_register is not defined for each on of JS files, Splunk adds "i18n_register({"plural": function(n) { return n == 1 ? 0 : 1; }, "catalog": {}});" which cannot be found. How can I handle it? Thanks!
