Destination folder already exists
During installation or update of our product, you might see an error message similar to this:
Installing plugin from uploaded file: smartslider3-wordpress-PRO-3.x.x.x.zip
Unpacking the package…
Installing the plugin…
Destination folder already exists. wp-content/plugins/nextend-smart-slider3-pro/
Plugin install failed.
This problem happens, because a previous installation or update went wrong, our folder got created, but the files in it weren't. You should go to the FTP of your website and delete the folder:
Free version: wp-content/plugins/ smart-slider-3
Pro version: wp-content/plugins/ nextend-smart-slider3-pro
You don't have to worry, your sliders will stay!
