Upgrading to WordPress version 3.5

A word of caution before you update! This is a major WordPress upgrade. Certain plugins or themes could break your WordPress site. Before you push the “Please update now” link, be sure you have a full backup of all your site files and database.

One of my favorite tools for backing up WordPress is the *

Some plugins are already being reported to us that have issues with WordPress 3.5, including the scan function of the Wordfence Security plugin. I am sure that plugin developers are working feverishly to get them ready for version 3.5.

People ask me all the time, “Is it safe to upgrade WordPress now?” The answer is simple. If you are not using a plugin or theme that will conflict with WordPress 3.5 then you should be fine. Check your plugins and theme to see if they are compatible. Copy your site over to a test environment and try the upgrade there first. You certainly don’t want to break your “live” site.

UPDATE 12/12/2012 at 12:50pm CST:

A big thank you goes out to Mark Maunder, the developer of Wordfence Security, for notifying us via email, in which he points out a new security enhancement in WordPress 3.5. Nice!!

If you’re wondering why many of your plugins are emitting the warning:
“PHP Warning: Missing argument 2 for wpdb::prepare()”
WordPress changed a policy in their code. They started requiring a second parameter when plugin authors call the wpdb::prepare function. They made this change as a security feature to help prevent SQL injection attacks.
WordPress plugin core developer

Andrew Nacin has a nice writeup

that gives some detail on why the change was made.
Mark just released an update for the


Security plugin update to fix this issue.
