Embedding Blocks Into Non PHP Files
Pulse relies on PHP includes to embed blocks, galleries and the blog. This means that the target page has to end in .php in order to work. But what if your site uses .html pages? You have two options to get Pulse working. The easiest option is simply to change those files from .html to .php. If this is not an option for you, then you can also force .html files to be parsed as PHP. Just add one of the following lines to your .htaccess file. Depending on your server type one or the other may work. Try both, one at a time, and use whichever works.
AddType application/x-httpd-php .html .htm
or
AddHandler application/x-httpd-php .html .htm
