web-to-lead form of suitecrm is not working in wordpress


I have created a web-to-lead form in SuiteCRM and copied the generated raw HTML to a page created in WordPress admin as a single page post. However, the form is not working. In chrome JS console, I see an error

“Uncaught TypeError: Cannot read property ‘lang’ of undefined in
sugar_grp1.js?v=L_gZ2lJDSmg-RmlYIZH3Lw:128 (anonymous function)”

The submit button is not working at all which I believe is due to this error. Any help is appreciated.

SuiteCRM: Version 7.2.1 WordPress: V. 4.1.1 PHP: v. 5.4. Running on Openshift.com.
