Just loaded SSU. Clicking on Extras/Simple SEO URL Manager in Admin brings up a blank page.

Error logger shows that mydomain/admin/ssu.php is trying (on line 13) to call mydomain/includes/classes/ri_template.php. I checked, and ri_template.php doesn't exist in my implementation nor in SSU 3.7.5 download files (i.e. no ftp problem on my end).

Was this supposed to be ytemplate.php (which is in that directory)?

Zen Cart 1.38a
SSU 3.7.5

Please Help. Thanks in advance.
