Web Design and Development
With WordPress regularly cranking out new versions and updates, upgrading your WordPress-driven website has now become a regular occurrence. Or perhaps, it has become a regular annoyance.
Fortunately, upgrading your website is not particularly difficult, even for a first-timer. And WordPress even supplies plenty of documentation to help you get it done. (See the short WordPress upgrade guide or the extended upgrade guide.)
Unfortunately, the guide does not sufficiently cover the problems that may occur during an upgrade. So we have listed a few problems below and some potential fixes.
If your blog is blank right after your upgrade, see our article on this topic: Uh Oh! My WordPress Blog Is Blank!!!.
If you can't log in to the admin area, there are two potential fixes:
Oops! This means that you have probably overwritten or made erroneous changes to your wp-config.php file. Open the file and verify that all of the information is correct. If you have upgraded from a very old version of WordPress (ie. earlier than 2.5), you might want to compare the structure of your wp-config file with the current upgraded structure which has introduced additional security mechanisms.
Usually, upgrading your site via the automatic upgrade is as simple as clicking the Update Now button and waiting for the process to complete. But sometimes it doesn't work. Some reasons why the automatic upgrade fails is:
Sometimes after upgrading, all pages other than the home page throw Page Not Found errors. This is usually due to the .htaccess file and your permalink structure. To fix this, reset your permalink structure by reverting to the default structure and then switching back to your desired permalink structure. This will rebuild your .htaccess file, and should hopefully fix any Page Not Found errors.
One great thing about WordPress is that there is a large community of people who use it. So if you've had a WordPress-related problem, it is likely that someone else has had this problem and has found a solution to solve it. To get experts or other WordPress users to answer your questions, simply start a new thread on the WordPress.org support forums.
