[HELP] Permalinks Structure in Clipper WP Theme

[Waves]

Hello to you all, I'm having a problem with permalinks structure with this theme Clipper. Happens that I can't set it properly so consequently I'm obligated to use the default one that in the medium-long term may affect my SEO.

That's why I'm posting this thread to see if someone can help me with this, I'll be very grateful and will give rep in exchange.

So in short, if someone knows how to set a SEO friendly permalinks structure for Clipper please let me know.

Thanks in advance.
