Fatal Error in helper.php

That error happens when you have a template override for the SCLogin module. Please check your /templates/ireview/html/mod_sclogin directory. If there are any files in that directory, it means you've overridden the output of our SCLogin module.

The call to getForgotUser was removed in the 6.1 release and shouldn't be used anymore.

You should update your overrides by comparing them to the changes in the /modules/mod_sclogin/tmpl directory and incorporating any changes from the new release into your overrides, or incorporating any changes you need into our original files.

I hope that helps explain, but if you have any other questions, please let me know.

Thanks,
Alex
