Protocol Error Code

Safari is not able to open up a page. I have been on this specific website before. This has only started being a problem as of yesterday.

I am receiving, "The error is: The operation couldn't be completed. Protocol Error ( NSPOSIXErrorDomain:100) "


Someone please help

Safari/Preferences/Advanced - enable the Develop menu, then go there and Empty Caches. Quit/reopen Safari and test. Then try Safari/History/Show History and delete all history items.  Quit/reopen Safari and test. You can also try try Safari/Clear History…. The down side is it clears all cookies. Doing this may cause some sites to no longer recognize your computer as one that has visited the web site.


Are you running any anti - virus programs? Using a VPN?


Try setting up another admin user account in System Preferences/Users & Groups to see if the same problem continues. Please post back on whether or not this worked. Also try the Safe Mode. Please post back on whether or not this worked.
