Website hosted on 1and1 only display index.php
<p>I recently suscribed to a 1and1 hosting contract. I've been having issues to display my website, so I tried to put some very basic pages online in order to tell wether the issue was in my file or on the server side.
The homepage is named index.php and has a link to another page (page1.html) that is supposed to display a "Hello World".`     </p>

<pre><code>&lt;a href="page1.html"&gt;Clique&lt;/a&gt;
</code></pre>

<p>The homepage is online but there are some issues.</p>

<p>The homepage only works when it's called index.php and doesn't work when it's called index.html.
When I click on "Clique", the url changes to mywebsite.com/page1.html but the content is still "Clique" while it should be "Hello World".Also, the CSS file isn't read.</p>

<p>I've read a lot of threads dealing with similar issues and apparently it might be a problem with the .htaccess file. I don't have a .htaccess in the folder where my files are and I don't know much about how it works. Also, the CHMOD is 705 for both files.</p>
