Error on Paypal check out page

[Cjsim]

Hello,

I have set up paypal express on my 1.3.7 Zen cart version,only I get an error page when try to use the paypal in my website,it comes up like this.

Warning: array_merge() [function.array-merge]: Argument #1 is not an array in /home/jayelegi/public_html/includes/modules/payment/paypalwpp.php on line 1467

Warning: array_merge() [function.array-merge]: Argument #2 is not an array in /home/jayelegi/public_html/includes/modules/payment/paypalwpp.php on line 1467

Warning: Cannot modify header information - headers already sent by (output started at /home/jayelegi/public_html/includes/modules/payment/paypalwpp.php:1467) in /home/jayelegi/public_html/includes/functions/functions_general.php on line 44

I did contact paypal they thought it was a extra line or space before <? or after ?> but after contacting my hosting technical team they checked and there is not extra lines and said it had to do with the coding.

Any help on this would be good,

Thanks in advance.

Welcome to Zen Cart.

Unfortunately there was an error in the first edition of the module, causing the message you mention.

There is a patch update available here:

Grab the latest from that list, since it includes all cumulative fixes related to PayPal services.

Good luck with your shop !!!

You upload the unzipped files to your website, replacing the existing files by the same name. The folder structure in the zip file is the same as the folder structure on your website.
