Deploying Jupyterlab notebook with voila on apache http server

Hi!
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
