Apologies for the delay in reply.
Responsive blog theme has inbuild slider. So, there is no need to use the plugin.
– The images used in the slider comes from the post. You will have to create posts and add featured images to it. Select category for all these post and save the changes.
– Now go to Appearance–>Theme option–>Responsive Blog Home Page.
– Check “Enable Custom Front Page” option.
– Move to “slider section” and select the slider category for the “Choose post category for slider images” option.
Save the changes and check the result.
Let me know if you are still facing the issue.
