I have upgraded my magento from 188.8.131.52 to 184.108.40.206 . Now I can not find any extension files.
I have to set all extesion files in "includes\src" folder.
Please advice me how can I solve this issue
It requires good debugging to be honest. All I can recommend is to check a server specific things, like: include path settings.Have you tried to run in in different server environment?
You are trying to upgrade Magento from the Connect Manager, right? When you are appling the upgrade is there anything displayed on the console screen in Manager? If so, Try to solve that. It will help you fix the issue.
