Text formats all look the same? I am using the CKeditor and IMCE modules. 

When in edit mode, I can see the following text formats in the dropdown menu under the body text area:


Filtered HTML
Full HTML
Plain text
PHP code


I am logged in as an admin, selecting different text formats from the dropdown menu does not change anything on the page. For example, selecting Plain text, doesn't remove the icons at the top of the text area. What am I doing wrong/missing?

Selecting the PHP code option however does change the appearence of the text area in a sense that the icons disappear.
This is expected behavior.

The "Text Format" Select List affects the way drupal parses and displays the data after it has been saved and is being displayed to the end user; not the way it is saved nor the way it is displayed on the Node Edit form.

By default:

Given Input:

&lt;div&gt;
  &lt;h1&gt;Title&lt;/h1&gt;
  &lt;img src="foo.fpg" /&gt;
  &lt;?php echo 'bar'; ?&gt;
&lt;/div&gt;


"PHP Code" filter output

&lt;div&gt;
  &lt;h1&gt;Title&lt;/h1&gt;
  &lt;img src="foo.fpg" /&gt;
  bar
&lt;/div&gt;


"Full HTML" filter output

&lt;div&gt;
  &lt;h1&gt;Title&lt;/h1&gt;
  &lt;img src="foo.fpg" /&gt;
&lt;/div&gt;


"Filtered HTML" filter output

&lt;h1&gt;Title&lt;/h1&gt;
