I just want to let you know that there is a Server Error with 2.11.2.
[SEVERE] Could not pass event SSLinkEvent to SignShop v2.11.2

Not sure what it means everything works fine players are able to buy and sell from shops but if they interact with a sign it puts out a long error message I would post the whole thing here but its a lot.

I have been good at keeping records of versions of plugins and spigot when I update the server or add new plugins so I have that if you need it.

Also, the spigot version is 1.12.1 build 60.

If you need any further information let me know I will check back here in a couple days and see if there is a reply, if not then you can contact me via the email below as I rarely get on this website so I don't know if I get an update on this issue or not.

Without the stacktrace, we cannot help.

where can I find that?

Ah, that would be the

it puts out a long error message I would post the whole thing here but its a lot.

that you were talking about

2018-04-08-5.log
That's the server log not sure if that's what you are looking for when you say stacktrace.
Also, it only happens when making shops by the look of it, I tested it in survival and creative both give the same error.

I restarted the server before causing the error to happen.

probably easier to read if you open up the log with notepad++

Ah, yep. This looks like it's a duplicate of one of our other tickets: #47 It's related to a change in the Residence API. Thanks for the second report.
