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.<\/p>\n\n\n\n
1 Created a fresh WordPress Multisite installation (subdomain mode). 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\/ , it should support multisite.<\/p>\n\n\n\n Some of errors in error log:<\/strong><\/p>\n\n\n\n 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.<\/p>\n\n\n\n Thanks in advance!<\/p>\n","protected":false},"template":"","class_list":["post-18924894","topic","type-topic","status-publish","hentry","topic-tag-multisite"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/18924894","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic"}],"about":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/18924894\/revisions"}],"wp:attachment":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/media?parent=18924894"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
What I have tested:<\/strong><\/p>\n\n\n\n
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.<\/p>\n\n\n\nWordPress database error:
