mhash() undefined confirm php page
Working on transferring my client from remote to local checkout, when I looked at the source of my confirm page (trying to diagnose a pop-up problem), I see this error:
<input type="hidden" name="x_fp_timestamp" id="x_fp_timestamp" value="<br />
<b>Fatal error</b>: Call to undefined function mhash() in <b>/home/muirheadfoods/public_html/WA_eCart/checkoutScripts/WA_simlib.php</b> on line <b>30</b><br />
How do I fix this?
