After login - On the dashboard, I have Syntax Error popup shown with error code as shown in the image below:
After enabling debug mode On I have taken this screenshot.
Also, I have tested for 3 more users, they are not getting this error.
My moodle version to 3.6.4+, updated one month ago and I am getting this error from 4 to 5 days back. I have also not done any change in the core files of moodle as well as not installed any plugin from 15 days.
Is this a moodle 3.6.4+ vulnerability or something else? Anyone, Please help.
