We just upgraded a small multisite/subfolders wordpress3.4.1 -->3.4.2 and got a bunch of errors on the wp-admin/error_log
Please have a look here: http://pastebin.com/WzHUQeHf
The site seems to work fine (?????).
Could someone please explain what those errors mean, if there is something we should fix and how to do it?
Thank you in advance,
