Fatal error after upgrading to Wordpress 2.5
After upgrading DavidChinPhoto.com to Wordpress 2.5, everything seemed fine initially.
But when I tried going into the Dashboard / Site Admin, I got this error message:
Fatal error: Call to undefined function register_sidebar() in /home/ ... /wp-admin/includes/dashboard.php on line 12
Searching Google for “Call to undefined function register_sidebar()” turned up this discussion.
The solution that was proposed included disabling the Disable WordPress Widgets plugin, and that was directly applicable to my site as it was running on a 3-column variation of the K2 theme.
I took the following steps.
Step 1 - Edit an existing post
I was wondering how to get to the plugins page since I wasn’t able to call up Site Admin. By a stroke of luck, I thought of trying to edit an existing post, and it worked. I was then able to click on the Plugins link.
Step 2 - Deactivate the Disable Wordpress Widgets plugin
This a pretty straightforward step. Just scroll down the page until you see the Disable Wordpress Widgets plugin, then click on the Deactivate link.
Step 3 - Navigate to the Dashboard
Test that everything went well by clicking on the Dashboard link at the upper left-hand corner. You should be able to see the brand-new Wordpress 2.5 Dashboard now.
After this experience, I think I’ll just stick to the Default Wordpress Theme and modify the design and functionality to suit my needs.
