ruPlsRename - rename, move and copy files and folders

[Amid]

The plugin does not work.
Debug Console: not callable ruPlsRename::footer
Current GS Version: 3.4.0a
Can anybody help?

Hello, Amid! I corrected the plugin for this version, it is not known why it does not call classes in add_action, keep the link.

Thank you! Now the problem is fixed.
But there is one more problem
I can not create new folder in "Files" (upload.php).
And the folders created before in the folder "uploads" do not appear now, but they are still accessable via FTP.
Can you tell me, what to do?
