Web AppBuilder Deploying to Website

[Anonymous User]

I have created a Web AppBuilder through ArcGIS Online. I then log onto the Web AppBuilder for Developers and download the zipfile. I unzip the file and place the contents on my server. When I go to the URL, all i get is the loading screen that never goes away. See below.

I tried following the instructions here. Deploy your app—Web AppBuilder for ArcGIS (Developer Edition) | ArcGIS for Developers 

Step 4 is adding a proxy. Everything in my web app will be public, is it still necessary to do this?

Then it ask to register your app online. I tried to doing this, but i think im getting messed up on the URIs. I entered https://[myserver]:port &  http://[myserver]:port, but i still got the loading screen.

This is my first time hosting a web appbuilder and any help would be appreciated.

I changed more_normal.svg and more_hover.svg to .pngs within the Widget.js within LayerList folder within the Widget folder.

And your app worked fine with that change before you moved it to the production server?

Yeah, everything on the test server loads up fine and works the way it is intended. This is what is confusing me the most. I figure there must be some setting on our production server that is causing the issue?

Can you try deploying a vanilla (unchanged) WAB app to you production server and see if it works OK?

Could it be a Cross Origin Resource Sharing (CORS) issue, just because it works on the test server but not on the production server?

I checked on it the website today and everything loaded up fine on production. I wonder if had do with the server replicating. Thanks Robert for all your help.
