When the credit card processor's script breaks there are a few common problems (none of them directly caused by Strongbox) that you may face, for example some of your users (specially new ones) may not be able to login to your site if the processor script is removed or is unable to modify to your password files or databases. In those cases Strongbox will be just the messenger of an external problem, but not the cause of it.
After checking for the above problems, if you are not able to get it fixed feel free to contact us. Please let us know what you've done to try to resolve the problem, what site you're talking about, and provide FTP information. Note that an error from the credit card processor's script is not Strongbox related, so a support fee may be charged. See our Support policy at https://www.bettercgi.com/support/
