Just tried out v2.9.2 on Zen Cart 1.52rc2 (local install, Xampp 182, php5.4.16) and the mysqli issue rears its head (as pointed out here http://www.zen-cart.com/showthread.p...41-mysql_query)

Warning: mysql_query() expects parameter 2 to be resource, object given in blah blah\dev\zc152rc2\mailhive\common\functions\osc_database.php on line 76 -

select configuration_value from configuration where configuration_key = 'MAILBEEZ_MAILHIVE_UPDATE_REMINDER_TIMESTAMP'

[TEP STOP]
