I have met this issue while upgrading from PHP 5 to PHP 7 . I have checked all the problems and finally find out that it was mysqli PHP extension issue which was not enabled. If mysqli is not available WordPress 5+ detects this and will instead attempt to connect to the database with deprecated mysql_connect() calls. This will come out a misleading error message about mysql_connect() function not being available (since we don’t want this function).
