Could someone please point me to the RESX file in Languages where the main Login text for 'User Name:' resides?

I cannot find it. When I think I find it, and change a value, the text does not change on the Authentication/Login screen.

An upgrade from 4.5.5 to 4.6.2 overwrote my language customization.

Here's what the browser souce points to:

<span id="dnn_ctr_Login_Login_DNN_plUsername_lblLabel">User Name:</span>

All indications point to: \admin\Security\App_LocalResources\Signin.ascx.resx

Key: plUsername.Text, but when I change that, the Restart Host, close browser, even reboot server: still: User Name: persists.

Changes have been necessary due to refactoring, when extracting the login into authentication providers, other keys have been moved \DesktopModules\AuthenticationServices\DNN\App_LocalResources.

Tikkune wrote  This is a new Key since 4.5.5, and a new RESX place from which User Name: is being pulled. DotNetNuke needs a Language Editor Search feature. If you do any language customizing, it's frustrating looking for text by clicking in/out of Language Editor folders AND files. If you have access to your server, you can do a text search there, if you have a good text search tool. But then you might just as well edit RESX files directly at the file system rather than through Language Editor. I posted this enhancement suggestion recently at support.dotnetnuke.com; hopefully Language Editor Search is coming soon.

I agree - and so does the new localization team - but this requires development resources or getting this feature donated by a community member.
