I don't believe so, I have added a screenshot below of the original settings, back when it was on version 4.

I guess these have been carried through?

I could provide screenshots of the SQL tables, if you advise me which ones you want to see.

I think FriendlyURL, as this is present in the web.config file;

 <friendlyUrl defaultProvider="DNNFriendlyUrl">

      <providers>

        <clear />

        <add name="DNNFriendlyUrl" type="DotNetNuke.Services.Url.FriendlyUrl.DNNFriendlyUrlProvider, DotNetNuke.HttpModules" includePageName="true" regexMatch="[^a-zA-Z0-9 _-]" />

      </providers>

    </friendlyUrl>

Because this site is being inherited, I can't way anything for certain :)

Let me know if there's another way to 100% confirm the answer.
