I had things working pretty well but downloaded 5.5.1 and now I cannot log in to my site. When I upgraded, the site reset to the default plain yogurt content and now I can't change it.

I get the following error message:

My Site

Fatal error: Call to undefined method ImageBlockController::generateNav() in /home2/dyslexi1/public_html/concrete/blocks/autonav/view.php on line 3

Any help you can give would be very much appreciated.

Thanks!
