conflict themes?

I viewed your site on Chrome and Firefox but can’t find any abnormalities. Can you elaborate what you mean by random display errors?

the menu don’t show the background button but a simple list… ??

The home page and the internal pages are using different stylesheet.
Home page: https://www.myapp.netsons.org/wp-content/themes/HomePage/style.css (with background image for menu)

Internal page: https://www.myapp.netsons.org/wp-content/themes/iIng/styleIng.css (without background image for menu)

Since I am not familiar with the theme, I have no idea how to fix it.

but all the 2 themes are background image…. ??

ul.menu li a {
	display: block;
	width: 119px;
	background: url('images/menu.png');
	padding-bottom:11px;
	padding-top:12px;
	}
