I have a slightly older site that I havent updated in a few years and now when I try to edit any of my posts I'm getting this error as well as this error information:

The editor has encountered an unexpected error.

There's some sort of Javascript error going on obviously but I wouldappreciate some guidance on fixing the problem since this is the first time I've encountered this kind of problem. Thanks in advance!
