How to Turn Excerpt Off in WordPress 2.9.2

1. Log in to your WordPress account.
2. Click 'Appearance' on the left-side menu bar of the admin control panel, then click 'Editor.'

3. Look at the list of posts on the right side of the page. The ones you need to modify are called archive.php and index.php. The archive.php file controls the appearance of your category, tag and archive pages, and index.php controls your main index page, which is usually the homepage of your site.
4. Click 'archive.php.' The code for this page now appears in the center area. Select all the text in the editor, and paste it into a text editor such as notepad. Do not use a word processor such as Microsoft Word, as this will add additional code to the file. Save the file to your computer's hard drive. Now you have a backup, so if you make a mistake you can easily replace the file with a working version.
5. Return to the WordPress admin screen and scroll through archive.php in the central editing area until you find the line of code containing 'the_exerpt()' (without quotations). This may be surrounded by php tags, like this:

6. Replace the word 'excerpt' with 'content,' so the code looks like this: 'the_content()' (again without quotations), then scroll to the bottom of the page and click 'Update File.'
7. Go to your blog's main index page, followed by a category page, to confirm that the posts are displaying in full. If they are not, return to the code and ensure that the changes have been saved correctly and that there are no typing errors.
