adamjz on "[Plugin: Real-Time Find and Replace] Haze theme"

I cannot replace the "Read more" button in this theme, or maybe it's the WPBakery visual composer, not sure. I also tried .po .mo translations, altering php in theme and plugin files, and some basic javascript regex (really basic tho, i'm a beginner). Neither worked. Do you think it's possible to translate it?
