Thread:Extension talk:LinkedWiki/XML error: "Undeclared entity warning" at line 174 (parsing as UTF-8)

Hello. When I try a local query:

I can get this error: Error #sparql :Array

Also I could get the following data (touching some code for debugging):

=
LinkedWiki: Using ARC2_SPARQLXMLResultParser

=
Linked wiki Error: Array (   [0] => Array        ( [0] => XML error: "Undeclared entity warning" at line 174 (parsing as UTF-8) )

)

Can you give some line about that?

Thanks.
