The calendar display sign up sheets plugin is not working on our newly launched website. This is appearing in the php log:
[06-Mar-2024 14:49:41 UTC] PHP Warning: Undefined array key “jquery-ui-theme” in /chroot/home/aa94ffba/0b5859785b.nxcli.io/html/wp-content/plugins/pta-volunteer-sus-calendar/admin/class-pta-volunteer-sus-calendar-admin.php on line 83
What should we do next? Thanks for your help!
