Crypt() on windows under nginx (wpn-xm) does not work, where to dig?

Question

PHP

Good afternoon, I installed wpn-xm.org
, configured all the paths, set up my site and I get the error Message: crypt(): No salt parameter was specified. You must use a randomly generated salt and a strong hash function to produce a secure hash. Which means that it cannot generate a hash. Everything works under linux. Under Windows, no. What can be done to run crypt()?
