    6.0.5 Login Error - Data at the root level is invalid. Line 1, position 1.

    Hello

    I have an Umbraco instance running for a couple of years and now I have the following YSOD when I login to /umbraco:

    Data at the root level is invalid. Line 1, position 1.
    
    [XmlException: Data at the root level is invalid. Line 1, position 1.]
    

    Anyone able to assist me?

    Thanks in anticipation, Paul

    Hi,

    I had the same issue.

    In my /config/trees.config file the line 1 has a "invalid" char. Notice in the image the incorrect "font".

    enter image description here

    this is the normal one

    enter image description here

    Check other config files in your solution for the same error.

    Best regards, Pedro Adão
