If you are using any WordPress plugin that connects with Twitter, you should update to the latest version that supports OAuth. Otherwise the plugins are not going to work. I personally use “Twitter Tools” plugin on my client’s Blogs and in some of my sites and I updated to version 2.4 for full compatibility with OAuth. You need to register each of your sites using this plugin in Twitter. (see picture above). The great news is that you can use your site’s name where it says: “about 10 minutes ago via WpThemesPlanet in reply to WordPress”. Instead of “BlackBerry” or “TweetDeck” You can see your own site’s name.

With this new feature, you still individually approve each application before using it, and you can revoke access at any time. To see which applications you have authorized or to revoke access, just go to the Connections section under Settings.

In order for Twitter applications to access your account, developers have been able to choose one of two authentication methods: Basic Authentication or OAuth. Both require your permission, but there is an important difference. With Basic Auth, you provide your username and password for the app to access Twitter, and the application has to store and send this information over the Internet each time you use the app. With OAuth, this isn’t the case. Instead, you approve an application to access Twitter, and the application doesn’t store your password.

Besides Twitter WordPress plugins, many other apps, including Echofon, TweetDeck, Twitterrific, Seesmic, and Twitter for Android, iPhone, and BlackBerry, are already using OAuth. The same feature explained above, applies for all these other applications.

I tried the following HTACCESS and it fixed all these problems with broken or missing images:

#Wordpress Multi site
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
 
# uploaded files
RewriteRule ^files/(.+) wp-includes/ms-files.php?file=$1 [L]
 
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule . index.php [L]
#END WordPress Multi Site

If you are using The Donncha Domain mapping plugin to allow users to use domain names, make sure to update to the latest version that is compatible with WordPress 3.0.x. Otherwise you could see this message when a blog user tries to login:

“You don’t have permission to view this site. Please contact the system administrator.”

To update to the latest version of Donncha’s domain mapping plugin:

WordPress 3.0 Domain Mapping 0.5.2

If you notice any other issues after updating to WordPress Multisite, let me know and I will see if there is any fix.

New features in this WordPress release include a new default theme called “Twenty Ten”. Let me add that it really looks like “Patagonia” Theme, so I guess less people are going to use my theme, time to “adapt and change” I guess. But in the other hand I can feel proud to work as inspiration to whoever designed Twenty Ten.

Theme developers have new APIs that allow them to easily implement custom backgrounds, headers, shortlinks, menus (no more file editing), post types, and taxonomies. Developers and network admins will appreciate the long-awaited merge of MU and WordPress, creating the new multi-site functionality which makes it possible to run one blog or ten million from the same installation. Also, I really don’t understand why would they merge WpMu into WordPress, since most people are going to use normal WordPress anyways.

You can download the RC and test it out if you want, directly from wordpress.org

Some things to take in mind:

_Custom menus are finished! Yay!
_Multi-site is all set.
_There are a ton of changes, so plugin authors, please test your plugins now, so that if there is a compatibility issue, we can figure it out before the final release.
_Plugin and theme users are also encouraged to test things out. If you find problems, let your plugin/theme authors know so they can figure out the cause.
_The look of the WordPress admin has been lightened up a little bit, so you can focus more on your content.

Enjoy!

It’s one of the most exciting features in the coming WordPress 3.0. It gives you full control over your site’s navigation menus. Users can easily drag and drop items, to create menus that include any mixture of links to internal pages, external URLs, categories, basically a customized widget. Then you can embed these custom menus as a widget, in the sidebar, footer, etc.

You can either install or update Patagonia and Tandil theme automatically from your dashboard. This is recommended if you didn’t change anything in the css or php files manually. Otherwise, make you sure to save your customization before upgrading.

Happy WordPressing everyone!

They are releasing it now rather than waiting another week, because they wanted to get people testing it during this weekend. There’s a lot of new stuff going on in WordPress 3.0, so this time they are giving you a list of things to check out, to make sure people are testing all the things that need it.

You Should Know:

_The custom menus system (Appearance > Menus) is not quite finished. In Beta 2, the layout will be different and a bunch of the functionality will be improved. You can play with making custom menus, and report bugs if you find them, but this is not how the final screen will look/work, so don’t get attached to it.

_WordPress and WordPress MU have merged. This does not mean that you can suddenly start adding a bunch of new blogs from within your regular WordPress Dashboard. If you’re interested in testing the Super Admin stuff associated with multiple sites, you’ll need some simple directions to get started.

Happy WordPressing!
