Co-Authors Plugin & Poseidon Theme

Hi Tom,

Thanks for using Poseidon Pro.

As paying customer you can always contact us on https://themezee.com/de/kontakt/
We usually answer emails within a few hours, but monitor the support forum for the free theme only weekly.

Integrating Co-Authors Plus requires a child theme and some own PHP functions. I have written a basic tutorial some time ago on my blog: https://themecoder.de/2017/04/20/mehrere-autoren-und-gastautoren-fuer-wordpress-beitraege-hinzufuegen/

If you need help with the exact functions please contact us on https://themezee.com/de/kontakt/

Cheers,
Thomas
