As there has been some issues apparently, could you please confirm the procedure to update my plugin to new version manually?
I have already downloaded it from Envato market place
Thanks and regards
Remove the old version. Extract the paid archive and install 3d-flip-book.zip from the extracted folder.
What about existing books?
You mean manually by copying files or by using install of wordpress?
Books are stored in the database. They are in save. Using WordPress default interface.
