Hi Tom!
Thanks for taking the time to report this.
I have just tried that on my end and you are right. It does not work using that path. It seems the path documented in the template file is wrong.
Try using the following path and see if it works for you:
[your-theme]/tribe-events/shortcodes/my-attendance-list.php
I have logged a bug report for this so it can be addressed in one of our next maintenance releases of our plugins.
I will set this thread’s status to “Pending Fix” and link it to the report. This way, we will notify you once a fix is released.
We apologize for the inconvenience and we appreciate your patience while we work on this.
Best,
Victor
