HTTP Status 500 When creating a custom view filter

I'm am an admin within our system, but, beginning today, I am getting a status 500 error (screenshot attached) when trying to create a custom view filter.  I have tried this in IE and Firefox, cleared cache and cookies in each of those browsers and am still getting the error.  I have had no problems with these filters for the past 3 weeks when we began using them.  There have been no updates done to our system since yesterday.  We are are running version  7.6.0 Build 7608
