I was not able to update the meta-box plugin from the wordpress dashboard. I had to re down load the plugin and install it along with the other 3 meta box plugins at the same time. This is the only way it would work for me. Any ideas why?
I think there probably was an error while downloading the extensions to your website. That might be caused by broken connection or interruption while downloading. The files you get when manually download and using the updater extension are the same. Please keep checking the next time and let me know if it still happens.
