A couple times this last week, we have been getting the following error (red bordered box pops up on payment page) when submitting a promotion code:
An error has occurred:
We’re sorry, but the promotion code could not be applied because the event cart could not be retrieved.
Both times I noticed there was an update to EE 4.9.3->.4 and 4.9.4->.6 and so I updated the plugin and it worked when I try again.
What is the cause of this issue and how do we fix it?
Thanks!

The cause of the issue is the line items from the cart have been deleted, which may be a caching issue on your server. Does your host include server level caching?

We have W3 Total Cache plugin installed but I have the registration-checkout page excluded. Do I need to exclude all the event pages also?
I also noticed the following errors when I click “Register for this Event” from the event page. This is on the top of the checkout page.

No. I had them turn off Varnish a couple months ago because it was messing up my SSL redirection.

I believe those new errors started after I updated to 4.9.6p. How can I revert to 4.9.4? I don’t see where I can download it.

You can update to 4.9.7, it includes a fix for the errors you posted above.

My site is not showing there is an update. I have forced it to check for updates but it still says 4.9.6 is the latest.

You can also download 4.9.7 from your account page.

I know that I can download it from your website, but the question is what is proper way to manually install an update. I have Googled it and I cannot seem to find a clear answer as to the proper way to manually or force apply an update.
