It is often that clients I have installed blogs for feel tempted to press the link at the top of their page “upgrade to the newest version of wordpress 2.8 “. In almost all cases the person doing the upgrade only presses the button but neglects to read or follow the small print. If you are going to upgrade to a new version of wordpress please remember to include these steps as well. In some cases I have seen the blog seize up and lock you out. Also make sure the person installing your blog gives you “administrative” access to your account.

Step 1 – Backup your MySQL database. ( You may need to contact your web host to help you to do this )
Step 2 – Upgrade WordPress – click on the button ” Upgrade Automatically”.
Step 3 – Upgrade your PLUGINS also.

If any of this is above your head contact your web designer and have them handle it for you!
