I have upgraded moodle version from 2.7 to 3.4. Configurable reports plugin is not working in moodle 3.4 version. It is working fine in moodle 2.7 and I am able to download and view the reports whereas in moodle 3.4 it is not opening and showing error "no such column". Kindly help me in solving this issue.
Configurable reports plugin is not supported in Moodle 3.4 yet. It is supported till Moodle 3.1
You need to either switch back to Moodle 3.1 or have to do some customization in code.
You can check the complete error by turning on the Debugging of the site. You can turn it on by - Site administration ► Development ► Debugging
