I'm revising the online reservation system for my B&B, and encountering an error on the secure server. When a guest submits a reservation online, their browser is supposed to be directed to a form on a secure server, for entering credit card details. The non-secured data associated with the reservation is transferred from the booking engine to the secure site, populating a page called SecureForm.html. The guest enters credit card details on that page.
There are two issues I'm encountering. First, there is a warning at the point when the secure site is supposed to open, "Warning! The website is not secured". The second issue is that the page on that server, for entering credit card details, does not load.
I've done my best to check scripts, paths and permissions, to no avail. The SSL certificate is fine, and it works with the existing reservation system which I am in the process of revising.
I've attached the error log from the secure server. I don't know how to interpret that log, but it appears there is an error reading the certificate.
