Hi All, I've been using a DNN portal to map several domains to my ISP hosting account

All of these domains redirect to the domain people-centered.org where the portal configuration then routes them to subfolders.

For example holodomor.org.uk is mapped to a folder named holodomor

The ISP made changes a few days ago which now prevents DNN Portals from working and with their  lack of understanding of how this works it is taking a lot of time to get through to them that they haven't fixed my problem.

If they can't resolve it, I have to move it somehow to another provider, which means copying over the entire structure.

Can anyone suggest what might be preventing the portal mechanism from working since they made server change?

TIA Jeff
   

Thanks Sebastian.
