Easier to just replace all files. This is what WordPress does actually.

I have just cleared : _site_transient_update_plugins from WP_options to force plugin update check, and there is still no update.

As I said – I will need Steve to chime in on how the system works but I don’t believe that transient controls anything. There IS a WP CRON task defined named ‘wp_update_plugins’ scheduled to run twice daily. My guess is that yours is not running at all. But that is just a hunch and based on the fact that WP Cron can fail so apparently easily and regularly.

Plugin has been updated, and gravatars are working.

Excellent.

given the issue you had earlier with accessing an offsite url (ie gravatars), you host may be blocking the url that wp and/or sp uses to compare versions for updates…

Thanks for the input, You are properly right. I will ask my host.
