[edit - update] I have done some further investigation and it 'appears' that it's the eWay payment option that is giving Firefox grief (but only in Hosted mode)? I have changed to several other payment options to test and everything works as it should.
Nathan, this may be a genuine bug that has not shown up as yet. (I don't know how many of your clients use this Australian gateway in Hosted mode with the following config?) It works in my Joom1.5 site with no apparent problems?!
Unfortunately I need to use the hosted eWay gateway method for my payments.
I'm having an issue with Firefox on a test site that is using the latest of all the software. i.e. Joomla 2.5, DTreg 2.7.17 where, when I go through the checkout to the billing/payment page where it says "Event Registration:My Cart" and click on 'Checkout', I'm then sent to the "Event Registration:Payment" page that 'stops' at the credit card expiry date fields. (see below).
If I use IE(9) to do the same thing everything works as expected?
Admittedly this is on a test site but I have a live site that is using Joomla 1.5 and DTreg 2.7.16a that works just fine with the same setup??
BTW I'm using Firefox 13 but have also tried an earlier version and have also used another PC to test and get the same result regardless?!
The differences between the sites, besides the obvious software versions, are that the live site uses SSL when doing the payment 'thing' while the test site is set up without the SSL for testing purposes only.
Really need to to be confident before I go live with this and the deadline is looming... any thoughts?
