I just followed the instructions on the WP super cache website: https://wordpress.org/plugins/wp-super-cache/other_notes/
Good luck with it 😉
I removed the plugin by hand and reinstalled it. Now it all works fine again.
Just uninstall bij using the uninstall buton in the plugin menu was not enough.

I have this problem as well.
Here the problem started when I clicked the option to delete out of date cached pages.
All pages went blank including the admin page. I changed the super-cache plugin directory on the server and the website was up and running again.
After uninstall the plugin via the plugin menu I reinstalled the plugin ans the prolem went back. It looks like the is been modified some (config) file..
Does someone have any clue?
