Why don't the pages of the site bear as it should?

What kind of files are supported?

Interlamellar normal or simple is supposed to be ending with Html or Htm files and SSI (server-side include) should end with. Shtml in order to display.

CGI files must end with. Cgi or Pl in case that were written by (perl).

PHP files also must end with. php to display. If you didn't specify the file name in the browser  when you type the URL , the server search for a page index will be

for example:

index.html, index.htm, index.shtml, index.php, and in the case of index.html and index.php in the same file or in the same place will be displayed index.html The reason for this that the order of presentation has been prepared in advance in the server this way. Please be precise when you rename the files, for example, index.html and Index.html and index.HTML are three different names.
