SSL problems with my GoDaddy server

Don't be afraid to demand compensation from them.

Ok. So I called GoDaddy and was able to get a $0.39 credit for the hosting outage. Not much, but maybe it will get their attention. I also re-explained everything on a recorded call, added up the probable cost of the lost business, (at least $4K) and threatened to move all my sites and my client sites to a new hosting provider that is more Zen Cart-friendly. The person I spoke with promised that a supervisor would listen to my recorded call. I am really not sure this will happen, or if it does, that it will do any good, but at least I tried.

BTW, any suggestions for a Zen Cart-friendly hosting provider?

I suggest installing these files, from the v1.5.4 zip:
/includes/extra_configures/set_time_zone.php -- and set the TZ in the top half of that file to your desired timezone
/admin/includes/extra_configures/use_catalog_time_zone.php -- no edits required to this file, since all it does is tell the admin to use the storefront file ;)
Doing that shouldn't cause any errors, but if it does, post the errors from the logs it creates ( to see the logs, read: http://www.zen-cart.com/content.php?124 )

Hot dog...that worked! Thank you so much!

Yes, that's the side-effect it will have, and if you don't fix it Paypal will eventually turn off notifying your store of changes.
Are there any debug logs related to the ipn handler? On v1.5.1 you'll want to look in both the /cache/ folder and the /includes/modules/payment/paypal/logs folder. You might need to turn debug logging on for it to record them. When it's processing IPNs it logs every step it takes to talk back to PayPal for acknowledgement, in order to evaluate failures.
Can't offer help if we don't know what the error message is ;)

That's good news. Thanks for your helpful information.

Nothing much in /cache/. I have turned on debugging for both PayPal Payflow Pro - Gateway (Debug) and PayPal Express Checkout (Debug). So we'll see what that turns up.

Just noticed that I am getting these messages only 1 x day, at just after midnight. Does that ring a bell?
