Hi, Shufflehound team,
Thank you for the answer. I opened the Install Plugins in Appearance. There is the Slider Revolution not available before I did not uninstall/ delete it. (I did not try to delete the plugin, because I am not sure, if the link will appear in the Install Plugins after deleting it) I saw some pictures in the blog, where already installed plugins are there with Status Installed. Will I see the Slider Revolution link in Install Plugins in Appearance after deleting the plugin?
One more information: The Jevelin theme was bought 2017 and activated not by me. The Slider Revolution was maybe not activated, because in the plugin screen I see the text Activate Slider Revolution for Premium Benefits (e.g. Live Updates). I am not 100% sure, but I think this text came late. At the beginning it was not available.
Waiting for your reply.
