I just solved the problem by chance. To solve it, follow this path: “WordPress Settings > Discussion > Avatar Display” Activate “Show Avatars” in this area. This error occurs when “Show Avatars” is disabled.
I’m getting the same error: “PHP Warning: Undefined array key 0 in /home/*******/public_html/wp-content/plugins/masterstudy-lms-learning-management-system/_core/lms/classes/user.php on line 613”
WordPress v6.6.2 with MasterStudy Templates (ms-lms-starter-theme)
Php 8.2 (I also tried with PHP 8.1 version.)
WordPress site health tool does not report any errors.
I opened a ticket via https://support.stylemixthemes.com and am waiting for their response.
