I installed the extension "SJ Xmas" on my test-site http://www.landvanreyen.eu/J33 and I got the error : "SyntaxError: unterminated string literal"
The site is with a paied template from Joomla Shine, but even changing some configurations, desactivating most of the modules, ... the error kept on appearing.
Therefor I tried the module with its default setting and the Protostar template. Still the error appears. You can see it in http://www.landvanreyen.eu/J33/index.php?option=com_content&view=category&layout=blog&id=8&Itemid=410
(In Protostar the SJ Xmas images appear, when you go to www.landvanreyen.eu/J33 switching to my JoomlaShine template, the error raises but without images).
