"Content is not allowed in prolog." error in clustered server

Question

We have an instance running with two clustered servers at oracle web logic app server.

One of the servers runs smoothly, but the other gives the error at the login page.

I checked the logs but got nothing, any idea where to look?

login page error:

com.sun.facelets.FaceletException: Error Parsing /content/templates/baseLayout.xhtml: Error Traced[line: 1] Content is not allowed in prolog.

Answer 1

Your file /content/templates/baseLayout.xhtml has probably got something dodgy in the first line - it should be something like <?xml version="1.0" encoding="UTF-8"?>
