Still having M 3.6.4 and latest version of CR.
I encountered following Problem:
When adding a plot Diagramm (circle) it shows up as Picture above SQL-Table as long as logged in as Admin.
That seems correct so far.
But when logged in with other role (teacher), this picture is missing and shows broken Link to an unknown Picture only. -Plot is unusable for me so that way-
What may be wrong with that??? Buggy???
