The Error: Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /home/content/28/4282028/html/wp-content/plugins/sharedaddy/sharing.php on line 4
I know what you're going to say, "Update your php to 5, you'll have to wait until the update, sorry"...
But I've already updated my php to version 5. I even called my hosting service to verify that it was updated.
I deactivated and deleted the plugin, reinstalled it...same error.
