We are now preparing to go live with our first magento project at my current work place. So, I am trying to make a list of things that shouldn't be forgotten during and after going live.
Here are few things that I have came across so far. Suggest me below in the comment section if I missed any critical step.
How to override Magento Observers?
Today's task was to show/hide M2ePro's 'Show eBay Order' button based on permission. Earlier I had done the similar task for 'Create RMA' button which was quite straight forward. But that rewrite didn't work this time as it was an Observer.
This is how I was able to hide 'RMA' tab and 'Create RMA' button from Magento order view page.
