# Multisite bug

 * Tutor LMS activates and works correctly on a standard single-site WordPress installation
   in the exact same hosting environment.
   However, when activated on a WordPress
   Multisite network, the admin area crashes with a fatal error.
 * 
   **What I have tested:**
 * 1 Created a fresh WordPress Multisite installation (subdomain mode).
   2 Installed
   Tutor LMS.3 Activated Tutor LMS on a subsite.4 Admin area immediately crashed.
   5 Tested Network Activation as well.6 Same result.7 Installed Tutor LMS on a 
   separate single-site WordPress installation using the same hosting environment,
   PHP version, database version and server.8 Plugin activated successfully with
   no errors and no warnings in the logs.
 * This leads me to believe the issue is specifically related to WordPress Multisite
   support. According to this thread :[https://wordpress.org/support/topic/multisite-support-410/](https://wordpress.org/support/topic/multisite-support-410/),
   it should support multisite.
 * **Some of errors in error log:**
 *     ```wp-block-code
       WordPress database error:Table 'vozo6565_wp337.wp6c_2_wp6c_users' doesn't existSELECT COUNT(*) as total_countFROM wp6c_2_tutor_orders oINNER JOIN wp6c_2_wp6c_users u ON o.user_id = u.IDWHERE payment_status = 'unpaid' AND order_type = 'single_order'PHP Fatal error:Uncaught Exception:Table 'vozo6565_wp337.wp6c_2_wp6c_users' doesn't existLocation:wp-content/plugins/tutor/helpers/QueryHelper.php:1134WordPress database error:Can't create table wp6c_2_tutor_coupon_usagesCONSTRAINT fk_tutor_coupon_usage_user_idFOREIGN KEY (user_id)REFERENCES wp6c_2_users(ID)errno: 150 "Foreign key constraint is incorrectly formed"WordPress database error:Can't create table wp6c_2_tutor_cartsCONSTRAINT fk_tutor_cart_user_idFOREIGN KEY (user_id)REFERENCES wp6c_2_users(ID)errno: 150 "Foreign key constraint is incorrectly formed"
       ```
   
 * We would appreciate any guidance, as Tutor LMS is currently our preferred LMS
   solution for a multi-country project requiring up to 10 site licenses.
 * Thanks in advance!

 * Hi,
 * Thank you for the detailed report and the testing you performed.
 * After reviewing the information you shared, the issue is related to WordPress
   Multisite compatibility.
 * At present, Tutor LMS does not officially support WordPress Multisite environments.
   Because of this limitation, issues such as incorrect user table references, database
   table creation failures, foreign key conflicts, and multisite-specific query 
   errors can occur when Tutor LMS is activated on a network site.
 * The errors you shared (such as references to wp6c_2_users / wp6c_2_wp6c_users
   and foreign key creation failures) are consistent with the current multisite 
   limitations.
 * For now, Tutor LMS is recommended for standard single-site WordPress installations.
   If your project requires a multisite architecture, we cannot guarantee stable
   operation or provide a supported workaround at this time.
 * We understand this may affect your evaluation for a multi-country deployment,
   and we appreciate your interest in using Tutor LMS.
 * Best regards,
   Dip SahaTutor LMS Support Team
