USAe-pay blank page error

Hello,

I've been getting this problem on my site since I've installed the USA e-pay api and installed the payment module via the zencart control panel.

I've been referring to the below threads to try and remedy this issue:
o- http://www.zen-cart.com/showthread.p...hlight=usaepay

o- This thread in particular is very similar but with a previous version of ZenCart, 1.3.8. I am using 1.5.1 : http://www.zen-cart.com/showthread.p...hlight=usaepay

I've gone through and applied the code inoculation for rogue searches, properly ensured that my usaepay files were placed in the correct directories, and ran the mysql file with phpmyadmin into its proper database.

I am still getting a blank page error after check out, and I think this could be a problem with the language files with USA e-pay.

My debugger's entries:
[27-Aug-2013 12:45:23] PHP Warning: implode() [<a href='function.implode'>function.implode</a>]: Invalid arguments passed in /home2/dsewell/public_html/store/includes/modules/payment/usaepay_api.php on line 244

Please let me know if there has been a fix for this buried in someone's FAQ or if I am having an EIC scenario. I will be brainstorming to myself on what the problem might be while doing some targeted searches for that same error code across the forums and beyond.

Any findings I'll be sure to contribute to this thread in an edit.
