mumamo-do-fontify errors in nxhmtl-mode

Greetings.

I get ths error:
mumamo-do-fontify-2: mumamo-do-fontify m=php-mode, s=2735, e=2955:
Symbol's value as variable is void: default
when I move up & down and HTML & PHP mixed file.

I'm working with the last beta from Lennart. I'll give you all the
additional information required. I'd like to help to make a greater
nxhtml-mode.
