Suddenly my icons disappear in ACP?

[tomwin]

I hade som strange behavior in my ACP and i culdn't figure out what the problem was. My meny icons start to disappear. I thought the problem was with the cache or some PHP functions. I allso translated my site at the same time but I could not first understand that this also affected the icons in ACP. A small tip is to be careful when translating because some ACP icons are also affected if you translate system words as an example:

system    menutab__members_icon     user

I translated the user to swedish and the icon of the Member in ACP disappear.

class="fa fa-user"

I am not sure if it is the same thing, but you may want to look at the posts here to see if anything is familiar to your situation: 

UPDATE: I don't think I clearly understood what you originally posted, but based on what @Meddysong said below, I don't believe thread above that I posted is related to your issue. 🙂

Yep, that will happen if the bit you translate happens to be a word which is the name of a Font Awesome icon.

You'll find them with language strings which start menutab__ . Don't translate the ones which end _icon. Only change them if you want the icon to change but in that case you're not translating; you're choosing the name of another FA icon.
