I've just done a refresh and I'm getting

"Your database appears to need patching to a higher level. See Admin->Tools->Server Information to review patch levels."

I refreshed the page again after that and got the original error

"Fatal error: Call to a member function on a non-object in /home/hampshir/public_html/current135/includes/init_includes/init_db_config_read.php on line 25"
