The new version of the plugin is terrible, as well as the tech support. I had everything working fine on the old version I bought. I had custom dark theme CSS and a custom dark theme toggle in a specific place.
A “specialist” from the WP-Dark team updated my plugin, after which the dark theme started to look just awful – a mixture of my CSS and your standard one, the switch moved down somewhere.
All my requests to tech support were ignored for a week, then they replied – that we are going on vacation. My site looks terrible because of your plugin update, and the backups before the update are wiped out.
I don’t recommend anyone to get in touch with your products. Tech support is just not there and every update breaks something.
