Hi djgolgol,
If you want to change the default site language to RTL language, you need to compile less CSS from the Backend > Systems > Site template styles > ja_morgan - Style 3 then enable the development mode option and click the Less To CSS button. Wait until the system is done and you can disable the development mode option to view your site.
And add the following code to the "/templates/ja_morgan/local/css/rtl/style-3/off-canvas.css" file:
.off-canvas-left.off-canvas-effect-4.t3-off-canvas {
-webkit-transform: translate3d(50%,0,0);
transform: translate3d(50%,0,0);
}
