I am seeing differences on customers different web hosts regarding the automatic plugin update functionality and I have not been able to find anywhere a list of specs for hosts in order for this feature to work.
Would be very useful with a list of requirements for the automatic update of plugins (and Core) to work.
How should the file permissions be for the installation - is safe mode off required (are there workarounds?) - any other requirements. I think a list like that would be super useful for all the hosts that want to become WordPress friendly.
The closest I came to finding information is: http://codex.wordpress.org/Core_Update_Host_Compatibility
Can you help out?
