Hi @paritosh89,

There may be a problem with your file permissions. Please check that they conform to what is noted here: How should file permissions be set? - #2 by ctgraham

File permission on public directory or the upload directory?
It set on files 755 and folders 644 that is the default permissions. Kindly suggest which type permission do i need to set.

Thanks

Also check Users & Roles > Roles and see that the reviewer role has the review stage checkbox ticked.

That is already done. Please suggest
