Got this error
Checking if patch can be applied/reverted successfully... ERROR: Patch can't be applied/reverted successfully. Done
Need help on this.
My guess is that you deleted or renamed the original
I reckon you should ensure that folder is here.
If it's not there, I suggest you download a fresh copy of your Magento version and copy that folder over.
If it's there, it could be a permission issue so I suggest you double check that too.
