There is a site that is written in smarty.
In the webmaster, the site gives a 409 response and, accordingly, is prohibited from indexing.
Through scientific poke, I found out that if you remove the RewriteRule ^.*$ start.php [L] line from .htacces, then the response code becomes 200, but index.html opens instead of the page I need, which is located in the templates folder. I do not understand at all which way to dig.
