66qrcode error 404

Good afternoon everyone, allow me to ask a question, someone has had something happen to 66qrcode, after installing it the main page works but then everything else returns the error
Server Error
404
Page Not Found
This page either doesn't exist, or it moved somewhere else.
I can't get over it, thanks in advance

Nope ! everything works for me but i think this problem come because redirection problems .
i don't know but try to install previous version and update it to latest version.
After this if you got same problem please share screenshot here and i will do my best to help you .
