Late update to Bullseye / Lighty Issue [Solved]

Just ran through the blog post here;

And have it mostly down however lightty still aint right. Get an Acces Denied web page error. Lighty log say

FastCGI-stderr:Access to the script ‘/http/index.html’ has been denied (see security.limit_extensions

(index.html has some php script lines)

security.limit_extensions = .php .html .htm

But this time that aint working?

Any tips?
