Using the latest release (184.108.40.206) or the latest 1.0 branch from SVN, trying to format pretty much anything using the Go syntax results in an
undefined offset PHP error.
I managed to work around the issue so far by duplicating the
STYLE/METHODS colors twice (so each array has 3 items).
I'm not sure why it seems to work fine when using the "Demonstration" textbox on the Geshi website...
