Re: [Semediawiki-user] Call to undefined function mb_strpos() - when using wildcards in queries

[David M. <dav...@un...>]

Thanks to everyone for their help. The solution was as you have 
described - just enabling the php_mbstring.dll, except that I took the 
opportunity to upgrade php and switch to ISAPI while I was at it.

Thanks again...


Regards,
Dave.
