Браузер не находит файл по прямой ссылке?

.htaccess нигде не завалялся?

попробуйте в .htaccess указать
RewriteRule "(^|/)\.(?!well-known)" - [F]

Lander, это в .htaccess

RewriteEngine on
RewriteRule !(txt|js|ico|gif|jpg|png|css|swf|flv|libraries|maint|admin|login|logout|reg|html|otf|xml|yml) index.php [QSA,L]
