Hello,
Our server firewall requests that I disable the follosing PHP functions: ini_set, show_source, system, shell_exec, passthru, exec, phpinfo, popen, proc_open
Would disabling them break SuiteCRM?
Any advice is welcome. 
Hello can anybody help me with this information?
Hi,
ini_set, phpinfo, passthru, exec, popen and proc_open are used in suitecrm 7.8… so don’t disable these functions.
I think you can disable the others.
p.s.
to know if one function is used in your suitecrm, you can search it in the source code of your crm installation
