hi all
anyone can help i’m new to ojs and i have a problem with Open Journal Systems 2.4.7.1
the problem is i cant show left sidebar even if i already add new block journal layout.and swap right sidebar to left nothing happen .
thanks 
Hi @Rizal_Bagus,
Rather than investing effort in a two-sidebar OJS 2.x layout, I’d strongly suggest considering an OJS 3.x upgrade. OJS 3.x doesn’t currently support two sidebars without modification – this is an intentional design decision.
