Hi! I have "inherited" a website built in Concrete5, and had to move it from a subdomain on our host to become the primary domain. The site displays correctly now (had to install fresh concrete5 on the primary domain, and then move the site in toto to get that to work). The problem is I cannot log in to the site to make changes. I can get to the login page (index.php/login) but when I try to login I get the following message:

Fatal error: Call to undefined method Page::inc() in /home/walbur5/public_html/concrete/themes/concrete/view.php on line 2

I looked at the file, and no clue as to what is wrong. And no error log to be seen anywhere to see if there is any more info.

Concrete5 is new to me, although I have worked on websites in the past and feel comfortable with other packages and plain 'ol html/css/php. So where do I go to figure out what is wrong with this? Thanks!
