SharePoint 2013 - Not working after config IIS to work with port 443 SSL

Hello everyone.

I installed Sharepoint 2013 Standard edition on a virtual AWS (Amazon Web Services) server which is running server 2008 Standard with SQL.. Everything was installed using default settings. Once it was installed, I configured a few users and groups for testing. At that point, everything was working perfect. Was able to login, go to my document libraries and was able to upload, edit and save documents with literally no issues.

One of my development team guys got it and made changes within IIS to make SharePoint use port 443 SSL. After than change was made, I can get logged in, and initially see the initial SharePoint screen with folders and document libraries.

The issue now is that anytime I try to click on a folder or document library, I get the following error:


Sorry, something went wrong
Method 'Upgrade' in type 'Microsoft.SharePoint.WorkflowServices.WorkflowServiceApplicationProxy' from assembly 'Microsoft.SharePoint.WorkflowServices, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' does not have an implementation.

Can anyone comment or give advice on this ? I was suppose to have this issue corrected last week and am running out of things to do.

Thanks !!
