No security updates or Safari install were made in the last 20 days, so I don't think that was the issue. Only thing it could be - because it's browser-related - is that I was trying some browsers to see which one is best for my PPC. Maybe some of them made that, I don't know...
Anyway, already archived/installed and everything works just fine now. It was easier and faster than I thought, only thing is that I have to re-do some configs but that's minor. Thanks for the help.
