Most of the users who have upgraded from 1.9.1 to 1.9.2 would have faced this issue. The Static blocks/widgets in the CMS Home pages and other areas were no longer displaying.
All the latest releases of magento 1.9.2 1.9.3 added a new feature to whitelist the static blocks in the Admin Panel. This prevented the static blocks display in frontend.
To Resolve this we need to allow the CMS static blocks to be whitelisted. Navigate to System -> Permissions -> Blocks Menu
Enter Your Block type in Block Name field. Select Is Allowed to Yes
