After installing SocialEngine 4 (4.8.6) on a Mac mini running Mavericks Server 3 and PHP 5.4.27, SocialEngine pukes with an error:
1 exception 'Zend_Db_Statement_Mysqli_Exception' with message 'Mysqli statement execute error : Duplicate entry
Read on for a solution!
The cause is two-fold:
1) SocialEngine expects a 32-character hash such as supplied by MD5;
2) PHP in Mavericks Server 3 uses SHA-512 as the default, generating 128 characters.
I’ve encouraged SocialEngine to support the vastly more secure SHA-512 hashing.
Until then, here’s the fix:
in /Library/Server/Web/Config/php/php.ini, comment out this line with a semi-colon:
1 session.hash_function = sha512
When testing this solution, make sure you delete the session ID in engine4_core_session in your database, AND delete the cookies for the domain from your browser.
