[Solved] Where do I get “Bug Information” to add to a question?

Add define('WP_DEBUG', true); to your site’s wp-config.php. That will cause errors, warnings, and notices (non-fatal warnings) to print to the screen. Those are the “debug information” so frequently requested.

It is not advisable to have this enabled on a production (publicly accessible) server but if you have to have the debugging information then you have to have to have it.

You can also add define('WP_DEBUG_LOG', true); and the debugging information will be written to a file named /wp-content/debug.log.

You can then add define('WP_DEBUG_DISPLAY', false); to prevent errors from printing to the screen as you can read them from the debug file.

So, in your wp-config.php you’d have:

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);

Your server itself may also keep log file. The location and names of these files vary by OS. On Debian Squeeze, Apache’s log is by at /var/log/apache2/error.log. On CentOS 6 it is at /var/log/httpd/error_log. Those have much the same information, but you may not have direct access to them depending on your host and hosting type– shared, vpn, etc. The database server may also keep logs.
