hello i create an account on your site and try to download your file (link bellow) no error downloading works
did you change something ?

Yes, external file was removed by mistake.
But this behavior (Call to undefined method FlexicontentController::setError()) looks not good.
We need to get some message, like "File not found" and send notification to the admin.
