I just upgraded a WordPress Network from 3.4.2 to 3.5.1. I went to Update Network (/wp-admin/network/upgrade.php), upon suggestion of the prompts. After hitting the Update Network button, I get this on the next page (/wp-admin/network/upgrade.php?action=upgrade):
Warning! Problem updating https://[hostname]/[nameOfFirstBlog]. Your server may not be able to connect to sites running on it. Error message: Peer certificate cannot be authenticated with known CA certificates
This is wrong. We are using a valid, non-expired certificate issued by InCommon Server CA, and it's issued to the correct URL for this server.
How can we get WordPress to ignore this bogus error?
