Hi,
I've installed the wplms_one_page child theme and I'm having problem with layout. Layout is totally different as compared to the demo.
Please tell me how to install it so that it will replicate the original One Page style as shown in demo.
Kind Regards.
In default theme you can make your homepage look like one page child theme, refer:

Also I want to recommend you to not use one page child theme, because there are outdated copies present there which conflicts with default theme.
Also we are going to remove the one page child theme from wplms in future.
