No longer ability to Share ..with el Capitan
I upgraded my OSX to El Capitan last night. Not only did it drop out all my iCloud accounts in Mail, but now on Safari I have lost the facility under "Share Menu" to be able to share/send links,pages etc to Mail or F-B or other recipients. I have tried the keyboard shortcut using Command key plus "i" to make it happen. It does nothing now.
Any ideas anyone? Thank you.
iMac, OS X Yosemite (10.10.1)
