While doing an incremental upgrade from Sugar CE 6.5.x up to SuiteCRM 7.6.x, somewhere in between the menus corresponding to new SuiteCRM modules (Reports, Workflows, etc.) are missing from the Menu / Module Grouping option in the admin screen.
One important detail: in other admin screen options, we can actually see the modules (named “internally”, like “AOR_Reports” instead of “Reports”).
Please see attached snapshot for more reference.
T.I.A. !
