To start with I installed the sams-whois php script on a non wordpress site and got it working correctly. The 4 digit code security image is displayed properly every time.
Now I am trying to get sams-whois working on a wordpress site. The two sites are on the same server so php gd is definitely installed and working. However when the page with sams-whois in wordpress loads, the 4 digit code security image is just a black line instead of a 4 digit code security image.
I have tried everything I can think of the get the 4 digit code security image to display but no luck. The sams-whois script can be downloaded from http://www.phpace.com/scripts/sams-whois in case anyone wants to have a look at the code.
The code I am having the problem with is in samswhois.inc.php on line 262 <img align="absmiddle" src="swsecureimage.php" class="swSecureImage" /> when I inspect elements with firebug and run my mouse over the problem spot a popup message says ‘Failed to load the given URL’.
Do you have any ideas of how I can troubleshoot this error message?
