my solution is not great.. it is an urgency solution.
I assume you are the only user in the backend and therefore it is not critical to bypass the access management rules in your admin system.
Open the file magento/app/code/core/Mage/Adminhtml/controllers/System/ConfigController.php
amend the 2 functions:
- protected function _isAllowed()
- protected function _isSectionAllowed($section)
at the end of this file.
first line write return true;
for instance, I write the first function below:
protected function _isAllowed()
Upload the file and try to log again, you should see the orders now. After this, you will need to work out properly how to amend the access management files. I have similar issues that I am working on right now. Will let you know if I have more clues.
