i think you did something wrong with the installation process

at my server i have running openser 1.2.2 also with serMyAdmin-0.8-BETA and everything works fine

note : if you are planning to use serMyAdmin so won't have  to use command line e.g openserctl as openser-1.2.2 still produce support for SERweb tables and there is a confilection  between SERweb tables and serMyAdmin tables (specifically phplib_id and id columns )

i think you should repeat the installation steps again at sermyadmin.org as recently some sections were updated
