W3 Total Cache has crashed and cannot be recovered

I used W3 Total Cache and at some point I tried to restore the “factory” settings, after that the nightmare began.

I am facing the below error every time I am accessing the W3 Total Cache options.

Minify Auto encountered an error. The filename length value is most likely too high for your host. It is currently 204. The plugin is trying to solve the issue for you: (solving …).
The setting change(s) made either invalidate the cached data or modify the behavior of the site. Empty the page cache now to provide a consistent user experience.

Then -after few seconds- I see this message

Minify Auto does not work properly. Try using Minify Manual instead or try another Minify cache method. You can also try a lower filename length value manually on settings page by checking “Disable the Minify Auto automatic filename test”

I tried to delete the plug-in completely and reinstall it but nothing changes.
The main problem here is that I dont have access in W3 Total Cache options, the screen is empty and I cannot check or uncheck anything, so I cant just Disable the Minify Auto automatic filename test…

Please help…
