When you log in to a site, the app reports an error like ‘\r\n\r\n\r\n Login authorized for fred’, but the site does actually login correctly.
This can be caused by a fault in your ‘functions.php’ file in the child theme folder. If you haven’t created a child theme, you can ignore this as a source of error.
You need to check whether that file finishes with the final statement and does not have a “?>” at the end, nor must is have any blank lines at the end of the file.
