After upgrade radius manager, you may see following error when you click on
Home / Settings
Unknown column 'pm_sagepay' in 'field list'
It is caused by in-correct table name
pm_netcash where as RM searches for `pm_ sagepay`. Issue following command to solve it.
Login to mysql, and change db to radius.
mysql -uroot -pSQLPASS use radius; ALTER TABLE `rm_settings` CHANGE `pm_netcash` `pm_sagepay` TINYINT( 1 ) NOT NULL ;"
Make sure to change mysql password. This will alter the in.correct table name to correct one and then you will be able to access the menu correctly.
