I just purchased your car dealer theme and can’t update the LayerSlider WP plugin. I don’t have a caching plugin installed. I’ve deactivated then deleted the LayerSlider WP plugin. I then tried to re-install and keep getting the error stating that the plugin needs an update.
In the latest theme release we have included the 6.6.2 version of the LayerSlider, you can redownload the theme bundle to get this version. All further slider version we need to check to make sure it works properly with the theme and then add it to the next theme update.
You need to redownload the theme bundle, and there you will find the 6.6.2 version of the LayerSlider in the plugins folder. Then disabled and delete your current plugin and then install the 6.6.2 version from the bundle.
