Thread:Project:Support desk/MediaWiki error : mcrypt create iv()

Hello, I am new to mediawiki, I purchased MediaWiki Hosting from Hostpaedia

Default installation works well but if i install new Media wiki on another directory than i got this error

Warning : mcrypt_create_iv on file : cryptRand.php on line 285.

I got to know from Hostpaedia Team that the Mediawiki hosting is hosted on Windows Server.

One of my friend using Windows Azure hosting and having the same problem.

Is there any bug in mediawiki for Windows? Please guide us.
