Hmmm, I have the very old free version 1.0.0.8 running under WP 5.6 without any issues. What´s exactly the problem you have with this theme ?
I have a paid version Fifteen Plus 2.0.
One of the issues is that my menu dissapears. So I had to install a wordaround with installing the plugin “Enable jQuery Migrate Helper” and this works.
The support doesn’t respond at e-mails and the Twitter-account hasn’t been used for more then 2 years.
I think that explains a lot.
That´s a shame, I have very good experiences with the Inkhive support team but this is two years ago. I updated to 1.1 in the past and my webpage looked like a disaster 🙁 The theme had changed completely and most functions that were the reasons why I decided to use it didn´t work anymore. So I rolled back to 1.0.0.8 and never touched it again, it still works under WP 5.6 and I´m more than happy with it. If you want to take a look: http://www.singlecoil-guitars.com
Cheers from Germany and Happy New Year to you and yours, may the force be with you !
