Q. I receive a message like «/usr/sbin/bconsole: Permission denied».

A. This is not a Webacula (or Bacula) bug.

First check: /usr/sbin/bconsole — is binary ELF file (not a shell script).
See also INSTALL file.

Next, modify your .htaccess file :

Create test.php :

And check this : http://localhost/webacula/test.php
See also /var/log/httpd/error_log

When you run test.php you SHOULD get a result like below.
If not, you do experiments with the system settings, PHP and your web-server.
