JH,
Thanks for the help.
Here’s the info:
Build: 20100810
.htaccess in the root directory: Nothing there aside from some old 301 redirects. Should there be something else? (If I need to write some mod_rewrite directives, I will, but I wanted to understand what was going on first) I even took the .htaccess file away for a moment to see if that made any difference.
Host: They are using: GoDaddy as their host, running PHP Version 5.2.14.
Here’s a specific example:
http://www.uproducers.com/
Any of the tabs across the top link to a template group. We didn’t need to use Force Query strings in 1.6.4. I currently have them enabled since the site is live, but I tried turning them off and changing the following line in the system/expressionengine/config/config.php file:
$config[‘uri_protocol’] = ‘AUTO’;
and change it to
$config[‘uri_protocol’] = ‘PATH_INFO’;
Didn’t seem to make any difference.
One final piece of info… When I enable template debugging (when force query strings is off), EE is searching for the template “index.php”—which obviously doesn’t exist, so it defaults to site/index. Thanks again for any guidance or insight.
