Hi! I have the same problem, but I have just deactivated all my plugins and it doesn´t work. I have installed Enfold Theme. The widget area doesnt work also and I cant add tags in post too.
At Enfold Theme has it own widget screen and I see some of them as these:
-Enfold Advertising Area
-Enfold Google Maps Widget
-Enfold Latest News
-Enfold Latest Portfolio
-Enfold RSS Link and Twitter Account
Someone has a solution? Thanks
