I did some research and realized that supee 8788 cannot be installed is you have installed supee 1533 update.
How should we patch when its throwing hunk error on the following line: app/code/core/Mage/Adminhtml/controllers/DashboardController.php.
Someone please provide step-by step instructions how to modify DashboardController.php file and install SUPEE 8788
That's been found & discussed here: http://magento.stackexchange.com/questions/140550/security-patch-supee-8788-possible-problems
They are talking about manual reversing of DashboardController.php, I lost how the code should look like after we revert 1533, install 8788 and again have to rever 1533 changes back. The last past is where I am lost. Anyone can post a copy how it should look?
We are experiencing this issue attempting to patch CE 220.127.116.11 and EE 18.104.22.168
Whilst the solutions offered by others in the Stack Exchange post may get you around the problem of applying the patch, surely Magento need to acknowledge the issue and supply a new patch?
As the workarounds are not the official word from Magento, we could be both failing to resolve the security flaw and introducing a new issue. This is also likely to crop up again in future upgrades or patches.
What is Magento's official response on this issue?
100% agree with cgan, I dont want to do workaround unless it essential. I hope Magento will release updated patch. Self made methods may hunt us in the future updates.
I looked at stackvoerflow solution
I have raised the issue with Magento and they say they are releasing a new version of the patch to resolve this issue.
