I just read your article How To Create & Edit The .htaccess File For Your Site. I have a similar issue.
I want to run a PHP script on a html page. There is a website xcommentpro.com which provides comment services for a website. There are two options to place comment on my html site, either I change my web page extension to .php or I configure my .htaccess file. Please visit this page and see the code to be placed in .htaccess file.
I dont know how and where to place the code in above the above page in my .htaccess file.
I contacted my hosting company regarding this issue, they are saying that I simply edit the Apache Handlers section in control pannel. I dont know how to do that either. They were telling me to add x-httpd-php in the headler field and .html in the extension field. I have done that but still I’m unable to run a .php script on my page.
