Error found : Opening and ending tag mismatch: link line 163 and head in country_module_list.xml file. Error found : xmlParseEntityRef: no name in country_module_list.xml file. Error found : Attribute alt redefined in country_module_list.xml file. Error found : Specification mandates value for attribute async in must_have_module_list.xml file. Error found : Specification mandates value for attribute crossorigin in must_have_module_list.xml file. Error found : EntityRef: expecting ';' in must_have_module_list.xml file.
