closed ERR_TOO_MANY_REDIRECTS message on lading page

Hi,
I get this error only on my index page, my Hosting company told me it has something to do with my .htaccess file. I guess i have to make some edits to resolve these issues please find below the content of the .htaccess file.

I resolved the issues by downloading a new .htaccess file from the jamroom source code and replacing it with what was uploaded.
