Admin Users cannot access Widgets

I too have this problem. Every time I select widgets I get taken back to the members login. If I enter my login details I end back at the home page.
I use wordpress 3.6 with shopperpress theme and deactivating all plugoiins makes no difference

I discovered the solution. Restrict Widgets cannot be network activated. It needs to be activated manually for each site. This makes sense because the primary site on my Multisite installation displays the Widgets link from the Dashboard for site admins. It’s only the additional sites that do not allow admin users to view the link.

Therefore, deactivate the plugin on the Network plugins page, visit your site Dashboards and manually activate them.

I found my solution simply by installing the Google Libraries plugin, sometimes its the simple things and please dont ask me why or how this fixed my problem

It shouldn’t fix the problem because Restrict Widgets is not multisite compatible yet. It should work installed on each site separately, but not multisite activated.
