    • Error while registering new user

    Posted by Loren Maxwell posts: 25 United States

    I did a fresh install of 16.2 and when I try to register a new user I get the error below. I've re-extracted the zip and reinstalled the database, but I get the same error.

    Tikiwiki is in a public_html/tiki folder and I have made no adjustments to it.

    Any help would be appreciated.

    Here's the error:

    Fatal error: Uncaught exception 'Zend\Math\Exception\RuntimeException' with message 'The RandomLib fallback pseudorandom generator is not installed.

    Got an answer off of Stackoverflow, but thought it might be of interest to the group here:

    http://stackoverflow.com/questions/42404281/tikiwiki-16-2-error-while-registering-new-user/42414303#42414303

    From the answer there, "it's due to an older version of PHP 5 which hasn't got the mcrypt extension enabled".

    The options (also from the answer there):
    •Upgrade to php 7 (probably not an option unless it's your own server)
    •Enable php-mcrypt for you php (also probably not possible)
    •Try again with a recent "daily build" 16.x tarball from dev.tiki.org
    •Or enable one of the other CAPTCHA methods on Control panels->Security->Spam Protection, such as ReCaptcha or CAPTCHA Questions
