Twenty Twelve Title Contain No Spaces

There is a conflict between the Twenty Twelve WordPress and the All in One SEO Pack plugin. When the plugin is installed and you happen to be using the Twenty Twelve theme, the result is, there will be no space between your site title and blog title. You’ll notice this if you look at the title bar of your browser. After a couple of searches, I found a fix online. It involves editing the Twenty Twelve functions.php file and commenting out line 185 which contains the code below.

You will need to change:

add_filter( 'wp_title', 'twentytwelve_wp_title', 10, 2 );

and comment out:

// add_filter( 'wp_title', 'twentytwelve_wp_title', 10, 2 );

Also, you need to clear your browser cache to see results.

Tricky WordPress Multisite Setup

I was converting a regular WordPress blog to a Multisite blog the other day. I got stuck in the part where I needed to edit the wp-config.php file. I applied the changes to wp-config.php as suggested in the installation instructions. The problem was I wasn’t seeing the Multisite menus you would normally find under ‘My Sites’ inside the WordPress Dashboard. The installation instructions tells you to add the following lines to your wp-config.php file.

/** Enable WordPress Multisite */
define('WP_ALLOW_MULTISITE', true);
define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', false);
$base = '/';
define('DOMAIN_CURRENT_SITE', 'domain.com');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);

It was a silly mistake on my part. I placed these entries at the end of the wp-config file. It is important that these lines remain above the absolute path statement and before the wp-settings are loaded. See below.

/* That's all, stop editing! Happy blogging. */
 
/** Absolute path to the WordPress directory. */
if ( !defined('ABSPATH') ) define('ABSPATH', dirname(__FILE__) . '/');
 
/** Sets up WordPress vars and included files. */
require_once(ABSPATH . 'wp-settings.php');

Keep these lines at the end of the wp-config.php file.

WP-Admin Trailing Slash Problem

I had this WordPress wp-admin trailing slash problem for a couple of weeks now. When I don’t include a trailing slash after the wp-admin directory when logging in to WordPress, I will get a 404 missing page error. It’s a little annoying if you ask me, but it doesn’t really affect blog readers. It only shows up if you want to login to the WordPress Dashboard, and you forget to type the trailing slash at the end of wp-admin. Example below.

site.com/wp-admin/ <– this redirects to the WordPress login ok.
site.com/wp-admin <– this will result in a 404 missing page error.

So, I tried a couple of suggestions I found online, but the suggested changes to the .htaccess file didn’t seem to fix the issue. A couple of occasions, the suggestions were exactly the same code I already had in my .htaccess file. So, I tried a couple more suggestions. I noticed one blog post had a couple more lines in the .htaccess file that I haven’t seen in mine. So, I tried it and it worked. So, here are the changes I made.

I added these two lines to my .htaccess.

RewriteEngine On
RewriteBase /

I think the key code is in the second line. It basically establishes the base URL.

Regain Your WordPress Admin Account

So, I decided to get cute and changed my WordPress admin username to a username I wanted via a utility called phpMyAdmin. I went to the wp_users table and made a simple username change to the user_login field. I logged out and logged in back to the WordPress Dashboard. Disaster! I just lost both my WordPress admin and network admins rights. My former admin account has been reduced to a regular plebe. So, this is how a regular WordPress subscriber looks like.

It was a scary five minutes at WordPress land. I’m laughing now, but I wasn’t then. So, I went back to phpMyAdmin and also changed the user_nicename and display_name to the wp_users table hoping that would fix it. No cigar. Panic set in. After a few Google searches, I finally found the solution. Thanks to people who post their solutions online.

What a relief! First, you have to make sure you have the right user_id, especially if you have a multisite blog. Go to your wp_users table and make a mental note of your admin ID. It’s usually an ID of 1.

Next, I went to the wp_usermeta table and changed the wp_capabilities entry to a:1:{s:13:”administrator”;s:1:”1″;}.  The key here is the entry s:13. My account was reset to s:1 for some reason. I temporarily changed it to s:10, but it didn’t work. Setting it to s:13 did the trick. It worked wonderfully.

Now, I’ve regained all the admin rights for each blog that’s on the network, except that I’ve lost the Network Admin. Well, another Google search. Thank you. To make the story short, I also had to edit the wp_sitemeta table. Look for the meta_key and change to a:1:{i:0;s:11:”yournewname”;}. The s:11 is the length of “usernewname” which is 11.

That was the fix. Whew. A close shave. All in all, all is good once again at WordPress land. I am one happy admin. Just a bit on the adventurous side, but otherwise a happy camper. I’m posting this article because, I know some dufus admin in the future will probably do the same thing that I did. It wasn’t all that bad. It was just a little bit disconcerting when you lose all admin rights.

WordPress Blank Dashboard

I recently moved one of my blogs to Linode, a VPS hosting company. I noticed right away, when I logged in as admin, that the WordPress Dashboard, displayed a blank page. That’s not good. So, I started removing plugins by renaming the plugin directories until I found the offending plugin. Sure enough, it was a custom plugin I wrote myself.

Nothing has changed. The plugin hasn’t been touch. WordPress is the same latest version. The only thing that changed was the host server. So, I started looking into my PHP installation. What could possibly be missing? When I looked into my plugin code, I noticed some references to curl. I realized my server was missing a php5-curl module on the new host server.

A simple command to install php5-curl on the new server does the trick.

sudo apt-get install php5-curl

In this particular case, a missing module in PHP, caused the plugin to die unexpectedly, resulting in a blank Dashboard page within WordPress. Removing offending plugins temporarily fixes the issue, but it doesn’t get to the root of the problem. In my case, I was able to narrow it down to the missing PHP curl module that my plugin desperately needs.

In any case, everything is back to normal as expected, except for the blog, which is serving pages exceptionally fast, since I’m now running at Linode.
