Thread: Authorize.net Plugin Error - Fatal error: Call to undefined function mhash()

Authorize.net Plugin Error - Fatal error: Call to undefined function mhash()

I have Authorize.net all set up but I get this error whenever you try to check out using it.

Fatal error: Call to undefined function mhash() in /home/wyhomesm/public_html/wp-content/plugins/authorize-net/an-gateway.php on line 111


I set up the md5 hash in my authorize.net account and in the plugin.

Can you help me get it working please?
Sylvia
