I double checked this. I restored (custom > php.ini) disable_functions = exec,passthru,shell_exec,system,proc_open,popen,show_source then I removed all the exec,passthru,shell_exec,system,proc_open,popen,show_source from Advanced PHP Configure > Disable Functions. And doesn't work. My apps still show they're disabled.
When I removed it from custom > php.ini then it works. Am I missing something? This is not a new issue but it has been for a long time. But every time I update Kloxo-MR I have to go back to custom > php.ini and make the changes again.
