I have upgraded from magento 1.6 to 1.8 via magento-connect and now I have the admin links problem. Can’t edit cms pages, taxes, products, etc) . All the rest in the admin area works fine.
I’ve read many posts regarding this problem and tried with no success suggestions such as:
- manually uploading the 2 folders “Adminhtml” in /app/code/core/Mage/ AND /app/design (overwriting all files & folders);
- changing the permissions in /js/index.php file
- doing magento-core/Mage_All_Latest in Magento Connect
Does anyone have other ideas or suggestions on how to solve this problem? I would really appreciate all your help.
