Fatal error: Call to undefined function hash_init()

  • Hi! I just found Wordfence (through a friend’s recommendation) and am excited to use it. I am getting this error:

    Fatal error: Call to undefined function hash_init() in /home/xxxx/wp-content/plugins/wordfence/lib/wordfenceHash.php on line 343

    I am using php 5.2.17 and I did enable hash:

    hash support => enabled
    Hashing Engines => md2 md4 md5 sha1 sha256 sha384 sha512 ripemd128 ripemd160 ripemd256 ripemd320 whirlpool tiger128,3 tiger160,3 tiger192,3 tiger128,4 tiger160,4 tiger192,4 snefru gost adler32 crc32 crc32b haval128,3 haval160,3 haval192,3 haval224,3 haval256,3 haval128,4 haval160,4 haval192,4 haval224,4 haval256,4 haval128,5 haval160,5 haval192,5 haval224,5 haval256,5

    I tried uninstalling and reinstalling Wordfence, but I am still seeing this error at the top of my “live traffic” page.

    Any ideas?

    Check your PHP ini file where the function is probably disabled.

    Thank you for the idea.

    The global php.ini settings are showing it is on:
    ; Select a hash function
    ; 0: MD5 (128 bits)
    ; 1: SHA-1 (160 bits)
    session.hash_function = 1

    Could I create a new php.ini file in the WordPress files and add some code to override something. I also adjusted the MD5 to SHA-1 to see if that helped. I then turned the plugin off/on. No luck.

    Any more ideas?

    I noticed something else. On the same server – another user installs it without issue. I checked the permissions and they seem the same.

    Account 1: two sites. One works, one doesn’t.
    Account 2: One site. Doesn’t work.

    I thought maybe I had a plugin problem – but I deactivated all the plugins but Wordfence and it still didn’t work.

    ???
