Hi
The Ohanah component has problems with other templates too not only with joomlart templates
If you switch to Beez template for example the component doesn’t show correctly
so the issue is due to the component and not to the joomlart templates
The best way to solve these issues is to manage one at once all css files and php files for the positions
or switch to another component, also because i have found many other issues with this component and other templates
Calendar module not working — the event map not showing correctly the events etc etc
Again this component needs to be better tested.
