I have a nusoap server that was working fine and now despite no changes has suddenly started to return empty strings so my items look like:

    <item xsi:type="tns:Qualification">
           <ID xsi:nil="true" xsi:type="xsd:string"/>
           <Qual_Title xsi:nil="true" xsi:type="xsd:string"/>
           <Notional_Level xsi:nil="true" xsi:type="xsd:string"/>
           <Qual_type xsi:nil="true" xsi:type="xsd:string"/>
           <Main_or xsi:nil="true" xsi:type="xsd:string"/>
           <LAD_Aim xsi:nil="true" xsi:type="xsd:string"/>
        </item>

Those string used to contian information. I've checked that data is being returned by the query and i've tried bouncing the server/ services and clearing out caches but this hasn't helped.

I'm really confused as to why this would suddenly stop working and how to go about debugging this
