Backup the customized html file as a ".bak" file

[FTP]

Since the version 4.7.6, you can backup the customized html file as a ".bak" file, then it will be restored after an upgrade (in other word, the customized file won't be overwritten). For example, if you want to customize the file "webclient/login.html", you can modify the html content by yourself, and then just backup the file as "webclient/login.html.bak".

And here are the html files which support auto-restore:

/webclient/login.html
/webclient/main.html
/webclient/login_m.html
/webclient/main_m.html
/webclient/downloadpass.html
/webclient/weblink_update.html
/webclient/plugins/sendfiles/generate_weblinks.html

after customizing the html code like I have always done, I now get this message displayed to all users who try to access our site "You can modify the html file, but please keep the link 'wftpserver.com' at least."

why?

It means please keep some string like "Powered by wftpserver.com" in the login page.
