How to disable core reports

ProPanel reports have been merged into LearnDash core and since then there have been some reports of the admin area being slow. If you find that your admin screens are loading very slowly, it might help to disable the core reports.

To disable core reports in LearnDash, simply add the following constant to your wp-config.php file. This file is located in your WordPress files at the root. Login to your site via SFTP and navigate to the root of your WordPress install. Open the wp-config.php file and you can enter the constant below, right above the line that says /* That's all, stop editing! Happy blogging. */

define( 'LEARNDASH_MODULE_REPORTS_DISABLED', true ); 

/* That's all, stop editing! Happy blogging. */
