Should Envato continue to sell unsupported themes?
How long should non-updated themes be posted for sale?
I bought Dalton, a great theme in 2017, and my site was running smoothly and I was very satisfied with the theme and its functionality with plugins. The theme had been updated a couple of months before I purchased it, but not since.
So - as WordPress and Plugins continue to be updated and Dalton is not, plugins have started becoming incompatible, and I am forced to buy another theme and re-theme my site.
