Deploying Jupyterlab notebook with voila on apache http server

I’m have trouble getting the ipywidgets in my Jupyterlab notebook to show up when deploying with voila on apache web server. I have deployed the same notebook on mybinder and everything renders fine.
With the the apache server I am getting “failed to load resource” for .js and .css files. Any ideas as to the source of the problem? Thanks in advance!
Best, Mary
