500 Server Error upon Login or Logout

I'm new here and just installed and configured everything.

First problem is that I get a 500 Internal Server Error when I log into or out of Joomla front end now.

For example, when I log out, the page tries to redirect to this... dogwalkeracademy.com/moodle//auth/joomdle/land_logout.php

Website: dogwalkeracademy.com
Username: test
Password: test1234

Thanks for any help!

Is system check all green?

Check permissions for moodle/auth/joomdle folder and files. Error 500 could be caused by too permissive permissions. Set files to 644 and folders to 755.

Thanks for your reply.
The system check was not all green. I set file/folder permissions as you prescribed and now everything is green (except for Joomdle Web Services), and I no longer get the 500 server error when I login to the front end.

Thank you!

Great. You will need to make last check green before you can use Joomdle, though.
