Hi Omar,
I have got your email thanks for this.
I am replying here just so everyone else can see the response in case they come across similar issues.
I have now hidden the other menu once it reaches the breakpoint at 800px wide. The Responsive Menu doesn't target specific devices but rather device widths.
Meaning, this will show up on a laptop, desktop, tablet, mobile but only when the browser has been re-sized down to the specific width, which is why it usually thought of as a mobile menu as mobiles have small screen widths.
It can be used as a full site menu or just for mobile by targetting the different breakpoint widths, I have set yours at 800px.
I have also re-instated the main logo to the front page and centered it, for some reason you had set the display to none and floated left for this in the main style sheet. You had a few specific styles targetting body.home #et-logo so it was displaying differently on the home page.
Please can you check all is ok and as expected now, if not let me know of any other issues and I will try to help with these.
Many thanks
Peter
