I'm using OWB with MorphOS. Once I turned on my cache and all that jazz so I could remain logged into Hotmail, facebook, and the like, I found that I was suddenly no longer able to even log into these pages as I could before.
Now when ever I try to login I get:
Unable to open
http://Http://www.blahblahblah.comError 60: Peer certificate cannot be authenticated with known CA certificates.
Though I can log into Amiga.org thankfully!

EDIT: I also can not upload images to Amiga.org without getting an Error 59 I believe it was.
