• Shopkeepers version: 19aee4f (Compiled from Source)
• Spigot version: This server is running CraftBukkit version git-Spigot-0287a20-7560f5f (MC: 1.16.1) (Implementing API version 1.16.1-R0.1-SNAPSHOT)

If you have no shops, /shopkeeper list shows blank for "Page x of x".

• Start fresh with no shops.
• Do /shopkeeper list

The result will say "Page of ".

Should probably say "Page 0 of 0" or not show at all.

I have no interfering plugins (all the plugins on the server I made myself, or completely unrelated such as viaversion, plugman, permissionsex)

Might fix later depending how I'm feelin idk I found this while working on a PR for /shopkeeper list

Works fine for me: http://prntscr.com/tm5v60, http://prntscr.com/tm5xso
Have you made any changes to your config? Or maybe you updated the plugin and there have been config / message changes

That is really strange. I haven't modified any code or made any config changes.
Just wanna make sure you're also using the latest commit. It also seems to happen even when I've created shops.

Try deleting your config and letting the plugin freshly generate it. If this doesn't help, can you post your config?

Alright. Stopped server, deleted config, rebooted server and it was still broken.

HOWEVER I became suspicious of BLC because of how chat formatting has changed with 1.16.
I loaded up vanilla 1.16 and.... it worked. ._. How embarrassing I didn't possibly think that could be a conflicting thing until I added some logger lines to see the chat message after it was processed and it being totally fine with numbers.

To be fair I probably shouldn't be developing and testing on a modded client anyway.

Sorry about that!
Tldr: BLC Bug, not plugin error

I have no idea what BLC is, but I am glad you figured it out!
