Studies disappeared from the menu list after updating JATOS from to 3.5.11 to 3.7.3
Hi, we are having a troube updating JATOS from 3.5.11 to 3.7.3.
After update, the studies imported in the last 6 months or so have disappeared from the list (left side menu after login).
Running the studies from URL ends up an error ("A problem occurred:Unknown study or batch").
However, the folders and files of the studies seem still there, since when I try to import one of the study, it shows "Study import - but study assets' directory already exists."
Does anyone know how to solve this problem?
