Hi @arminunruh, thanks for your quick response.
I scrolled down, but there was no "broken theme" line.
I tried converting to other basic WP theme and that allowed me to delete the existing Lay theme and upload the new one you've provided.
And I was able to activate as you see below.
But I still don't see anything on my site.
I'm also thinking it's weird when I went to the key manager site for the latest files yesterday, I saw an unknown "Box####..." domain name under the activated site list, and my site is egndesign.com
Could that be a reason why I cannot make the Lay theme work on my site?
Let me know if you have other way to fix this.
Thanks!
