Per Placester Support representative:
To be completely transparent, this coming month we are going to stop supporting our free themes on WordPress and focus on our 6 premium themes that we offer to our IDX subscribers. Thought, even if you were running our premium theme on your own hosting you would need to update your theme semi-regularly to have any bug fixes take effect.
Hope this gives some insight.
Hopefully, this helps anyone else looking to start using Placester.
