Slider importing doesn't work on multisite
- Slider importing doesn't work, the slider won't be created.
Smart Slider works from its database tables. When you install a plugin on a multisite, it will create database tables for all of its websites, but if you add another site to your multisite later, it won't have those tables. The solution is to simply deactivate and activate the Smart Slider plugin, which will create those tables for all sites, which wouldn't have them.
If you wouldn't use the latest version, you could update the slider, as there were some multisite improvements in the latest versions.
