After the last update, the child theme for Gridiculous is no longer working - using it causes a blank site to load. Reverting to Gridiculous as the theme rectifies this.
Additionally the widget page is now dysfunctional - I can't drag and drop widgets, or expand the widget areas.
I have tried de-activated the plug-ins one by one, as well as all at once, to no effect. I have tried using the default Twenty-twelve theme and re-installing the update, which also does not resolve the widget issue.
The site is e-action.us and I don't want to leave the plugins deactivated because this site is in production. Right now it is in the default Gridiculous theme.
Thanks for your help!
