Describe the bug

When I connect to my server, I sometimes get this error in log:

You have some plugin running commands for you in the background. It would be useful to know what exactly is going on

@dordsor21 Hey, thanks for your reply, we do use the Plugin Titlemanager (https://www.spigotmc.org/resources/titlemanager.1049/) to display messages in the actionbar. E.g. using /tm amsg <player> <message>. At least this is the only occourence of the string "amsg" in out plugins folder. Did you mean that? Hope this helps!

[dordsor21]

Use /titlemanager instead of /tm

given the timestamps of the log messages don't really correlate to the other error, I guess this still needs to be addressed?
The only related parts are seemingly:

What is BSP? What happens when closing the shop inventory - or what happened in general? I do see another occurrence of the error with the connection from dords above - but there are seemingly other causes. Knowing what command was attempted to execute might help pin point the (argument) converter, which could cause the issue.

EDIT: And please share a full latest.log

BSP stands for BossShopPro (nowadays known as "Genesis" (it's a fork, since BossShopPro doe not get continued)). See https://www.spigotmc.org/resources/genesis-custom-gui-and-shop-creator-by-magemonkey-studio-formerly-bossshoppro.104824/
