I too been having problems with V3.6. Only thing is, after updating it, both backend an frontend of the site goes blank! I cant edit anything whatsoever. I took Pumka’s advice and renamed wp_safe_remote_get to wp_remote_get at the line 500 and the site is still blank. Thankfully my client understands that the internet isn’t perfect, but I need this resolved asap. Any more suggestions as to what to do?? Thanks.
