Thanks Ray - that did clear that first error message, but I still have the 2nd:
Fatal error: Uncaught Error: Call to undefined function mysql_select_db() in /webinfo/vhosts/manoa.hawaii.edu/docroot/ctahr/tpss/admin/courses_Insert.php:131 Stack trace: #0 {main} thrown in /webinfo/vhosts/manoa.hawaii.edu/docroot/ctahr/tpss/admin/courses_Insert.php on line 131
I see a number of mysql_select_db() function calls - one on line 131 and another on 90. Did the relational table SBs not convert to MySQLi?
