24 - Reference to function that was removed in 1.3
zMailMod version 0.9.9.5
When I open mail with debug logs on, I can see the following error:
Script Call failed - Error while calling [MassMailTimer.CheckMailResult]:
[string "Interface/AddOns\zMailMod\zMailModTimer.lua";]:159: attempt to call field 'IsBackpackFull' (a nil value)
The function EA_Window_Backpack.IsBackpackFull() was removed (I think in patch 1.3) from BackpackUtils.lua so it can no longer be used. In order to fix this issue you have to either create your own function to check if the inventory is full or check if there is any overflowing item (EA_Window_Backpack.overflowCount > 0) instead.
