I upgraded to 2.9.2 two days ago and lost all ability to upload images in posts, enter tags, and make changes to any widgets. After disabling all my plug-ins, it seems section widget was the culprit. If I disable it, everything is operational again.
But my site is now heavily reliant on the section widget plug-in - many pages and categories with specific sidebar content, all of which seems to be lost (not sure where the date for section widgets is stored to retrieve.)
I really need to get section widget functional again. Any help would be appreciated - website is http://www.enviroreporter.com
