Good evening, I would like to know if there is a possibility of including in the “index-files” folder all the libraries used in this beautiful work, because when you implement the error pages, if you do not have internet access it does not work…

Thank you, and excuse my audacity, but there is no other option when you do not have regular access to the Internet…

who will server without :joy: and if you want then you can make that library offline mode which is very small sized
