Hi I basically have a code/local/ of a core file I edited.
This was to add a "Company" column to the order grid.
Since updating to 18.104.22.168 and updating a few plugins around the site this has stopped working.
I am guessing another plugin is over riding my function or extending the class elsewhere?
I have had a look in the folders in my code/local/ but can't seem to find anything.
Is there a debug tool I can use in the backend of magento or a way of finding out what it going over my codes head?
