I would like to include some information about my discussion forum on my index.html page. I've notice that all the pages generated by CC have ".html". Can I rename this ".shtml" to be compatible with a SSI.php ?

You sure can! But are you using SSI and PHP together? Never heard about that before. People normally use one or the other. And the file extension for SSI is .shtml, and for PHP it's .php.

Depending on your Host Server setup, you can use php include without changing your page extension, meaning you can leave it at name.html.

This can be done by adding a small bit of code where you want the info to appear>;



Where info.inc is the codiing for the info you want to use, it can be written in normal html format.

Most servers are now already setup to be able to do it this way, but if not, just contact your hosting support and I am sure they will enable it for you.
