You should have a page that has the URLSegment 'home' somewhere on your site is what Matt means. You can check the database for this using phpMyAdmin in the SiteTree table.

It turns out I do have a page with the URLSegment as home:

1 HomePage 2007-09-09 11:27:23 2007-09-10 17:18:54 home

Any other possible suggestions?

I also tried Andy's suggestion to change the line of code:

if($this->dataRecord && !$this->dataRecord->can('View')) {

to

if($this->dataRecord && method_exists($this->dataRecord, 'can') && !$this->dataRecord->can('View'))

After implementing I receive the following error:

Fatal error: Cannot redeclare project() (previously declared in /home/.furbag/USERNAME/URL/sapphire/core/Core.php:80) in /home/.furbag/USERNAME/URL/sapphire/core/control/ContentController.php on line 104

Any thoughts?

I've added a number of custom templates and pages to the site I put up. Is there an easy way to save everything and just do a clean install of SS from scratch?

Sorry - forgot the bracket to start the if statement when I implemented the code...

This is the error I get:

Fatal error: Call to undefined method stdClass::buildCastingHelperCache() in /home/.furbag/USERNAME/URL/sapphire/core/ViewableData.php on line 187
