Cant Translate ‘READ MORE ‘ button

Hi, eveyone

I am wondering how can I translate the ‘read more’ button to Spanish ‘Leer Más’ that is under each product.

I have Loco Translate plug in but it doesnt appear the Read More text to translate and I cannot find the php template through FTP to translate it manually.

Hope you can help me!

Thanks a lot,
