I searched online for that phrase and got a lot of hits, but I'm afraid the discussions are over my head. I'm not a Unix/Linux admin, just a user. And even if I did understand them, it seems like in order to fix the problem, I'd have to have root access, which of course, I don't.
I think it's important that my old scripts and programs were working until today, so whatever broke them didn't happen during the upgrade.
Does anyone have a clue what happened? Thanks.
