This is the error taken from my !BugGrabber addon, it's coming up thousands of times and causing me the performance warning in chat:

are you using the latest version?

Yes, I keep all my addons up to date with twitch client?

Twitch showing as GatherLite-1.1.2-classic

thats wierd... you got any other addons enabled?

several, but this is the only one throwing an error

wich ones...

Ok so it seems to be my own addon, SniperTips in conjunction with your addon causes the issue, but neither addons throws the error individually.

dont know what to tell you....

78898x GatherLite\events.lua:41: attempt to perform arithmetic on local 'elapsed' (a table value)
GatherLite\events.lua:41: in function <GatherLite\events.lua:40>

Locals:
elapsed = <unnamed> {
 0 = <userdata>
 DoHooks = <function> defined @SniperTips\lib.lua:166
 OnApplyConfig = <function> defined @SniperTips\lib.lua:179
}

Judging by this, it looks like GatherLite is using the frame I have created in my addon.. not sure why.

shouldnt be possible...

Actually, I just found in my code I had a registration for OnUpdate that wasn't being used, SniperTips.frame:SetScript("OnUpdate", OnUpdate); - I have removed this and the conflict appears to be gone and both addons still work - AHA.. ok so your addon defines OnUpdate as a global function, makes perfect sense.

gr8

I would like to suggest you to not create your methods as globals, it's quite a common cause of addon taint :)

ill change it
