installed stack does not show in gallery
I take it you mean it does not show in the Stacks Library?? This can happen sometimes if you have multiple instances of the RW app installed on your computer that are different computers. Best way to install a stack is to drag and drop it onto the RapidWeaver icon in the dock (so start RW first). Then once installed, restart the app and see if it is in the library.
Thank you worked like a charm
