Do you have pop ups blocked? They may need to be allowed.
I have got the same problem https://chroniclesofelyria.com/forum/topic/15629/cant-pay-layaway.
I have the same issue.
Same issue. There is actually an error message above the area you put your information "Cannot purchase a package you've already purchased."
I have a fix in for this that will be deployed soon.
Please note, there were two issues with people making payments toward layaway items. We cleared off one, but one affecting people who are "Brew Master" tier to "Artificer" is still present.
We'll be working on another hotfix tomorrow.
