Hello Fabiancho
I trust you are doing well today!
Would you please let us know what functions of the plugin are not working on your site? Do you see any erros?
I’ve tested the plugin with PHP ver 7.0.8, and from what I’ve tested the plugin is working.
Please advise,
Cheers,
Nastia
I had the same problem. The W3 Total Cache Page cache is not working with PHP 7 and nginx (in my case).
In the error log files of nginx i had some error messages from the plugin. This issue/pull requests describes the problem:

Removing the & in the function definition resolved the problem and W3 Total Cache works now as expected.
