Php functions Disabled

I'm testing OS Property 6 locally on an Apache Web Server. Everything works except one thing. In Edit Profile, if I click Featured to make it Unfeatured, the JavaScript alert pops up but it stays Featured. If I click Upgrade Featured and select Unfeatured, everything works fine.

I saw that in System Information > PHP Setting > Disabled Functions there is this list: popen,exec,passthru,pcntl_exec,proc_close,proc_get_status,proc_nice,proc_open,proc_terminate,show_source,shell_exec,system,posix_getpwuid,dl

Is the problem here??

Hi Gerry,
The issue is not caused by the disabled PHP functions you mentioned. However, it may be a potential bug.
I recommend that you submit a support ticket and provide your site information along with an administrator account so I can check and resolve the issue for you.
Thanks
