"Prev" and "Next" sliding button on Testimonials

How do I relabel the "Prev" and "Next" sliding buttons on Testimonials - I need to change the word "Prev" to "Emuva" and the word "Next" to "Phambili"

 

Hello,
Please follow image to change them.

Thanks & regards
Pramod

 

Hi Pramod I do not see the js on the editor.

 

Hello,

Use WP Editor plugin to edit files, then you will see js folder and file.
