Let me preface this by saying I know absolutely nothing about coding, so sorry if I provide irrelevant information with the LUA error (giving all of it). It was originally only happening for me, but is now happening to all officers in my guild. Copy/pasting my curseforge comment, I posted that there before learning I should post it here. The date isn't today, but the error is the same. It is still broadcasting updates, we just cannot see the progress bar when we are doing it, and then of course we're hit with the LUA error as soon as we do press the button to broadcast.

I'm suddenly having an issue with the addon giving LUA errors whenever I try to broadcast DKP history to the guild or as individual people. I did not start having this issue until about last week. Addons is 2.1.2, not sure if the list of all addons is needed, but the error message is:

@dhalliday34 Looks like your your data got corrupted in any way. I am not the author and not deep into the code 🤔

Especially because you say it was happening just for you at the beginning.

So you can still use the addon as before? No missing entries or DKP History not showing correctly?

You could try to open the MonolithDKP.lua file in the WTF folder to check for anything unusual, but most likely that is not really a helpful as you have no coding experience, sorry.
