after installing the semantic media wiki extension and trying to run inline queries, I receive the following message when using '*' (e.g. in [[Release:=*]]): "Call to undefined function mb_strpos() in [SMWpath]/SMW_InlineQueries.php on line 416."
I wonder if this might be a server problem as I am running another wiki on another server and there everything seems to be alright. I'd be very happy if anyone could give me a hint on what's going wrong.

Thanks very much and best regards,
