Hi, I've been trying to figure this out for an embarrassing amount of time.
I followed instructions found here and managed to get Composer installed.
However, after successfully loading the 1st step of Anchor's installation wizard, I get:
ini_set(): session.configuration 'session.hash_function' must be existing hash function. sha256 does not exist.
system/session.php on line 11
#0 [internal function]: System\error::native(2, 'ini_set(): sess...', '/home/dh_47puyc...', 11, Array)
#1 /home/dh_47puyc/legit.gripe/system/session.php(11): ini_set('session.hash_fu...', 'sha256')
#2 /home/dh_47puyc/legit.gripe/system/start.php(36): System\session::setOptions(Array)
#3 /home/dh_47puyc/legit.gripe/install/index.php(33): require('/home/dh_47puyc...')
In my phpinfo.php file it says sha256 exists and is one of the "enabled" hashing engines.
I'm not sure how to proceed. I'm on php 7.0 and have attempted to enforce this version across my ssh environment, but could definitely be missing something since I very rarely need to do anything shell-related.
