Hi everybody.
Thank you for being so helpful.
I was using Xwiki StandAlone installation(.exe) for testing purpose, but
yesterday I decided install a Xwiki ready for production.
Everything was OK, except the Sucess and Error Macros.
In Version 5.3:

In Version 5.4

It appears to be some kind of CSS problem or something similar.
I'm not sure it's a bug or not. Let me know if I must create a Issue on
Jira.
I'm running Xwiki 5.4(latest) on Windows 7 32-bit(.war package) with tomcat
and mysql.
Thank you.
