WordPress 3.2 was released last week and with it came a lot of improvements. However, some of my clients and other WordPress users on Twitter have reported some Ajax issues with the drag and drop features of widgets.
Other issues included trouble uploading images and other media files for posts and pages.
I too fell victim to this on several blogs.
Update to the latest version of WordPress (3.2.1) released today. Then update plugins and themes.
After more than a million downloads of WordPress 3.2, we’re now releasing WordPress 3.2.1 into the wild. This maintenance release fixes a server incompatibility related to JSON that’s unfortunately affected some of you, as well as a few other fixes in the new dashboard design and the Twenty Eleven theme. If you’ve already updated to 3.2, then this update will be even faster than usual, thanks to the new feature in 3.2 that only updates files that have been changed, rather than replacing all the files in your installation.
Backup WordPress & Update Plugins
What eventually fixed everything for me was updating all of my plugins. I manually updated each plugin in the plugins section. There were some major updates needed. Nextgen Gallery plugin was one in particular.
Be sure to backup all of your files too. I use WP-DB-Backup which can be found here: http://wordpress.org/extend/plugins/wp-db-backup/
After you backup everything, be sure to update all of your plugins, themes, and WordPress. You should be all set.
