Translating problems

Hi,

Can you please tell me how to translate the plugin?
I try the following methods:
Translate wp_listings.pot file.
I create a .po and .mo files and then try different methods, I added them at a time in

• plugin languages folder
• in theme lang folder
• in theme languages folder

None of the above options worked out for me.

Can you help me please? What I’m doing wrong?

Thank you!
