Hi Zen cart checkout experts:

I have a serious problem with the checkout function with my online store at: www.mgpsos.com. I have been using Zen cart version 1.2.5 for almost 5 years. it worked very well until it was hacked september last year. Recently, I had to repblish the store to clean up hacker's code injected to the sites. After I republished all the files, I encountered a serious problem, the checkout function doesn't work any more. Click on the checkout button will always back to the main home page. Who can help me out? For testing it out, you can use following logon info:

Website: www.mgpsos.com

I'd appreciate your support, please email me at [email protected] if you have a solution.

Thank you very much in advance!
