With MW 1.18, the message [1] is shown in Special:Search for either $wgAdvancedSearchHighlighting = true; or $wgAdvancedSearchHighlighting = false; [1] Declaration of SphinxMWSearch::userHighlightPrefs() should be compatible with that of SearchEngine::userHighlightPrefs()
We had tested with 0.8.2, so using 0.8.5 should resolve the issue.
