Can’t see list of courses in the dashboard of Tutor LMS

Hello,

Thank you for reaching out.

To diagnose the issue, please enable WordPress debugging by following these steps:

1. Access your website via FTP or File Manager.
2. Locate and edit the wp-config.php file.
3. Find the line: define( 'WP_DEBUG', false );
4. Replace it with the following:
   define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );
@ini_set( 'display_errors', 0 );
5. Save the file and reload the Tutor LMS dashboard.
6. After encountering the error, locate the debug.log file in the wp-content folder and share its contents with me.

This will help me identify the cause of the issue and provide the best solution.

Hello @vrushalidigitcure,

Thank you for sharing the debug log.

Based on the error messages, the issue is caused by a custom function named custom_course_info_tab_name() in your TutorStarter theme’s functions.php file. To resolve the issue, you need to either remove or comment out this function.

I removed that code from function.php file. But still I can’t see course list in Tutor LMS dashboard. But when I started WordPress recovery mode, I saw the course list. However, as soon as I exited recovery mode, the ‘Critical Error’ message appeared again instead of the course list.

Also, in WordPress recovery mode, I saw the course list, but on the frontend, my site was down.

Hi,

Issue is solved. Thank you so much for your help!
