There are a bunch of WordPress plugins that claim to make your blog mobile friendly but after looking through a couple of them the WP-PDA plugin is the best. This plugin support multiple themes such as an iPhone theme and a PDA theme. The cool thing about this is the iPhone and Touch display things completely different than the typical PDA browser so this makes it easy to modify content specified on these two main mobile groups. You can download WP-PDA here. Trust me when I say that iPhone and PDA users that read your blog will appreciate this plugin.

In the admin of WP-PDA you can specify what browsers will use the mobile theme easily. Just visit the plugins link on the top right and you will see a link near plugin editor that is titled PDA. Just update the list and click submit for changes to take affect.

One thing to note is you will need to add your Google Analytics code to the footer of the iphone-theme and the pda-theme for those users to be tracked by Google Analytics. I have also posted an article relating to mobile Adsense ads with this theme so if you want ads check out this link.

Nagios is a great solution for monitoring hosts, networks, and services on one or more networks. Nagios will monitor as many services as needed per device and then will send an alarm if one or more services has an issue. By default Nagios monitors a bunch of services such as ICMP, HTTP, etc. but can easily be expanded by the use of plugins and other community based open source development projects where code is developed for a specific need and then shared with the development community.

I received the below two errors when viewing WP-Forum after an automatic upgrade via the WordPress admin plugin page.

Warning: file(<wp-root>wp-content/plugins/wp-forum/wp-forum.php) [function.file]: failed to open stream: No such file or directory in /home/question/www/www/wp-content/plugins/wpforum/wp-forum.php on line 33

Warning: implode() [function.implode]: Invalid arguments passed in <wp-root>wp-content/plugins/wpforum/wp-forum.php on line 33

After digging around for a moment I noticed that the automatic upgrade renamed the WP-Forum directory in wp-content/plugins from wp-forum to wpforum. After renaming the directory you have to go in and activate the plugin again. This resolved my issue with PHP errors being displayed in the forum.

If you are still seeing the errors after upgrading make sure you have WP Super Cache disabled.

The instructions for this plugin state to rename the wpforum directory to wp-forum so I just think the forum was not made to auto upgrade via the wp-admin interface.

The entire error I recieved was: Fatal error: Cannot redeclare tc_post() (previously declared in www/wp-content/plugins/text-control.php:20) in www/wp-content/plugins/text-control/text-control.php on line 33

When upgrading the WordPress plugin text-control I was getting this error when trying to activate text-control. I ended up remembering that the markdown.php had not worked on initial installation so I replaced it with the markdown.php from the WordPress plugin PHP Markdown Extra which resolved my initial issue.

Another item to note is the latest version of WordPress has a bug with the PHP ul function as noted by Michael Visser. This causes the following error to show up:
