Comment 17 for bug 1016791

The 'symfony' file is in the authpuppy file structure, in the root of the authpuppy installation, wherever that is. If you unzipped the authpuppy file to /var/www/authpuppy, then you need to

cd /var/www/authpuppy

and then run the

./symfony cc

And if after clearing the cache in the right directory, you still have the 500 error when creating a user, try removing the email validation. To do so, go to 'Manage plugins', then click the apAuthLocalUserPlugin and uncheck the checkbox that says 'Validate by email' and try creating your user. If it works then, it would mean you have a email configuration problem.
