Thread:Project:Support desk/Change the error text when read = false?/reply

This says solved, but in case anyone else comes across this:

You can find the message you want to change by adding  to the URL's query string.

For instance, if the page was http://example.com/wiki/Foo displays a message you want to change, then you can change the URL to http://example.com/wiki/Foo?uselang=qqx to find the message to change.

In the case of this message you would see  where the message would be displayed. To change the message, then, you would visit http://example.com/wiki/MediaWiki:loginreqpagetext and change the text there.
