Hi, tried to find this but have no joy. I recently moved a cs cart installation to a new server. All files moved over fine and everything seemed perfect. Problem is I now can not edit blocks in the layout or access the theme editor. The black column appears on the left but no options. In the layout I can not switch on/off blocks or edit content.
Turned out to be a an issue with modinizr. This was reply from CS CART
Thank you for your message.
The problem was caused by the following JavaScript error on the Design > Blocks page: Uncaught ReferenceError: Modernizr is not defined In order to fix the error I applied the changes to the js/tygh/core.js file of your installation and the error was gone.
I replaced this line: if(Modernizr.cookies == false) { with this one: if(typeof Modernizr !== 'undefined' && Modernizr.cookies == false) { in the js/tygh/core.js file.
