Removes error messages that appear in the center of your screen, such as not enough energy, not enough mana, out of range, invalid target, and all the other error messages that appear in the middle of the screen in red letters and basically just spam your screen.
It does not block the "Error Speech" that comes with them - you can disable that in Sound Options if you want.
By hiding error frame it will also hide the yellow quest progress text that appears in error frame (for example "boars killed 3/4"), you can always just use quest tracker for tracking quests :) Or if it's a big deal for you, try out addon called Errorfilter.

This addon is beyond simple, it only does this:
UIErrorsFrame:Hide();

Purpose is to remove the need to type that script command (or click that macro) every time you start wow.

Slash commands are available to temporarily show or again hide the error messages that this addon is designed to hide.
You can type "/er show" to show error frame and "/er hide" or just "/er" to hide it again.
(Instead of "er" you can also use "error", "eagle" or "eerror" )

Since addon errormonster stopped working i made this addon. This addon is written from scratch and is not based on errormonster addon which is much more complicated addon with more features. This addon will most likely never ever be broken by a patch due to it's simplicity in code, that's why I'm leaving it here on curse, in case more advanced error removing addons go out of date (like errormonster did), you can always count on this one to be here and to work :)
