We use Responsive WordPress Slider (2.3.0) on a website in combination with the MotoPress Content Editor Lite (3.0.7) and get this error in the browser console.
I could reproduce this on a fresh installation. It works fine until I install “MotoPress Content Editor Lite”. We would buy the Pro version, but the changelog only says “Improved compatibility with PHP 8.2.” and the site runs on PHP 7.4.
So will the pro version fix it, and it is just not mentioned in the changelog? Or is there another bug?
