Depends on how you perform the upgrade. I'd recommend backing up what you have and just try
git stash git pull git stash applyIt should probably just work, but you may get "merge conflicts" that you'll have to resolve.
In admin menu , on the left there is a category menu. Here, I am trying to edit or delete categories, there is a small icon directly on the right for each category name, but it is not working.
Do you have any ideas how to update / edit categories or how to fix this?
