Since these courses may be the only formal computer science courses many of the students take, we have chosen to focus on breadth rather than depth. The goal is to provide students with a brief introduction to many topics so they will have an idea of what is possible when they need to think about how to use computation to accomplish some goal later in their career. That said, they are not “computation appreciation” courses. They are challenging and rigorous courses in which the students spend a lot of time and effort learning to bend the computer to their will.
Step 1: Remove maintenance file
If you’re upgrading manually after a failed auto-upgrade, delete the file .maintenance from your WordPress directory using FTP. This will remove the “failed update” nag message.
Step 2: Update your installation
Visit your main WordPress admin page at /wp-admin. You may be asked to login again. If a database upgrade is necessary at this point, WordPress will detect it and give you a link to a URL like
http://example.com/wordpress/wp-admin/upgrade.php. Follow that link and follow the instructions. This will update your database to be compatible with the latest code. You should do this as soon as possible after step 1.
Step 3: Do something nice for yourself
If you have caching enabled, clear the cache at this point so the changes will go live immediately. Otherwise, visitors to your site (including you) will continue to see the old version (until the cache updates).
Your WordPress installation is successfully updated. That’s as simple as we can make it without Updating WordPress Using Subversion.
Consider rewarding yourself with a blog post about the update, reading that book or article you’ve been putting off, or simply sitting back for a few moments and letting the world pass you by.
Your update is now complete, so you can go in and enable your Plugins again. If you have issues with logging in, try clearing cookies in your browser.
