I can not delete a quiz attempt.
When I try to select an attempt and click the delete button, the attempts are still selected. It is not excluded.
I did the following, open the browser console to see if it displayed any messages and displays the following message:
SyntaxError: '[id = "<br />
<B> Notice </ b>: Undefined variable: regionbsid in <b> /data/www/html/unieuroonline/cead_grad/theme/lambda/layout/report.php </ b> online <b> 64 </ b > <br />
"] 'Is not a valid selector
Please, help me!
That error message is coming from your custom theme (Lambda theme). You need to report the bug to the people who make that theme.
