Advanced Duplicator linux server

Hey, I bought a server at elpis host.
I choosed linux, and I installed all my addons.
I have removed all the caps and all the spaces.
The tool is there, but I can’t save.
And everyone got that problem.
I’ve updated the tool to its latest.
Still dosn’t work.

Anyone got a fix for this?

You are using adv dupe 2, right?

Nope, I downloaded mine at

Search adv dupe 2 and download that instead of 1.
