Two days ago, I realized Magento 188.8.131.52 update to version 1.9.3 using Magento Connect (Mage_All_Latest). The process was all right until labeled in a certain way and now do not know how to continue it, because when I enter Magento Connect returns the error
Unable to read the configuration file
. I have backup of the database but not the system.
The site works perfectly, front-end and back-end.
Any solution to return to the previous version updating or how to enter Magento Connect solving that problem?
Thank you very much.
