Hi there,

major bug in sc9 latest version. in development enviroment i have the following code on a php button

sc_field_display({DAG}, 'off');
	sc_field_display({wk_eduarte_lesnr}, 'off');
	sc_field_display({wk_tijd_s_gesprek}, 'off');
	sc_field_display({wk_tijd_e_gesprek}, 'off');
	sc_field_display({wk_eduarte_lesnaam}, 'off');
	sc_field_display({wk_sbu}, 'on');

	sc_field_display({wk_subtitel}, 'off'); 
	sc_field_display({ronde_is}, 'off');
	sc_field_display({wk_st_id}, 'off');
	sc_field_display({wk_st_id_2}, 'off');
	
	sc_field_display({lk_id}, 'off');
	sc_field_display({wk_max_d}, 'on');
	sc_field_display({wk_locatie}, 'on');
	sc_field_display({wk_op_id_koppel}, 'on');

	sc_field_display({wk_werkvorm}, 'off');
	sc_field_display({wk_thema}, 'off');

sc_exit(sel);

also the save option in enbale grid mode works once and then stops working with no error in deployment in the devolpment it works fine.
after updating it works fine in development but in deployment the buttons don’t work anymore. debug shows nothing and there is no error code whatsoever just a not working button. please advice

If you generate code for PHP 8.1, it will likely not function under PHP 7.3. First, I would upgrade my production environment to 8.x and then try again. PHP 7.3 is fully end-of-life now.

i upgraded to 9.9.002 (15) i was told that this still works with php7.3 and that i have to install everything (seperate) again to use php 8.1
do i understand correcly that 8.1 is mandetory and i only have to change the server to 8.1 to get this working? because everything else i update the last fews weeks works fine. after the latest update things got wacky.
btw. where do you see that the version of your development enviroment is 8.1 or 7.3?
