Unable to login into admin after theme change I am new to Drupal and to understand the basics I created a new theme in Drupal and enabled it as default. It works fine, however, I am not being able to log in into admin. I reinstalled Drupal and the admin login works fine. When the default theme is enabled it works, but it doesn't work when my custom theme is enabled.
My .info file is -
name = My First Custom Theme
description = A custom them to understand how Drupal works
core = 7.x

stylesheets[all][] = css/style.css

regions[header] = Header
regions[content] = Content
regions[menu] = Menu
regions[left_sidebar] = Left Side Bar
regions[main_content] = Main Content
regions[footer] = Footer

And my tpl.php file is -
&lt;div id=&quot;header&quot;&gt;
    &lt;?php print render($page['header']); ?&gt;
&lt;/div&gt;

&lt;div id=&quot;menu&quot;&gt;
    &lt;?php print render($page['menu']); ?&gt;
&lt;/div&gt;

&lt;div id=&quot;wrapper&quot;&gt;
    &lt;div id=&quot;content&quot;&gt;
        &lt;div id=&quot;left_sidebar&quot;&gt;
            &lt;?php print render($page['left_sidebar']); ?&gt;
        &lt;/div&gt;

        &lt;div id=&quot;main_content&quot;&gt;
            &lt;?php print render($page['main_content']); ?&gt;
        &lt;/div&gt;
    &lt;/div&gt;
&lt;/div&gt;

&lt;div id=&quot;footer&quot;&gt;
    &lt;?php print render($page['footer']); ?&gt;
&lt;/div&gt;

I tried accessing admin page using following ways but without success -

http://www.mysite.com/user
http://www.mysite.com/?q=user

Any idea where I am going wrong ?
To quote you, it sounds like the answer to your question is you needed to:


  ...include &lt;?php print render($page['content']); ?&gt; in my tpl.php file.
  ...the drupal login form wasn't appearing on my site since no default
  region was specified.
