@rad8329 @geochr Can you try using onsenui-core.css instead of onsenui.css? That file does not import fonts so it should not throw errors. After that, you can import the fonts you need in your app manually so you don’t need to modify any dependency. All the reports about this issue are with Angular 5, I wonder what changed… I think ngx-onsenui is only tested with Angular 4 but I’m still surprised the font imports fail…
