Hi Scott,
For me its started 20.12.2020 as i member.
It is free theme and Colorlib support have been helping me a lot all these years, still nothing bad to say, just update it 
I hope you get this fixed, i had similar with even older sparkling theme and they give some solution to it.
Wordpress 6.0 is out and sparkling theme is holding back wordpress and php upgrade.I am still using wordpress 5.5.9 and php 7.4.x
Still good memories and first learining times i had with this theme. I just say we have strange times, i have used zero mask and no modern vaccine, so it stays, i am healty, all is well and will be well.
My plans are now to move flatsome theme, probably lifetime gpl version, without active support. Flatsome WooCommerce Theme 3.18.2 - Multi-Purpose Responsive WordPress Theme - GPLPlus
Maybe i still wait and hope for sparkling theme 3.x update, but i am not counting on it.
With gratitude,
Marx-Veix
