Ok I see that your Permalinks/URL’s are now working correctly instead of being completely broken like they were before. So that is good progress. It looks like you are using the Default links instead of using Custom Permalinks. ie ?p=50 which of course you do not want to use. Either select Post Name or enter the Custom Permalink structure tag like: /%postname%/ or use one of the other Custom Permalink structures.
Now what type of WordPress site is this? Is it a Network/Multisite subdomain installation?
