CMS Made Simple Forums

I've created the menu template frgrnav.tpl which is in database templates. When I place the command
{cms_module module='menumanager' template='frgrnav.tpl'}
to place a menu template in my page template
I get this message
'string(81) "Smarty error: unable to read resource: "module_file_tpl:MenuManager;frgrnav.tpl"" '
when I view the page.

Does anyone have any ideas what I'm doing wrong?

Don't use the .tpl ...

And if you are using newer ver. of CMSMS no need for all the calls...

{menu template='frgrnav'}
