Permission Error on /dev/shm

[primesoftware]

Hello all,
I am new to ZoneMinder, but not new to LAMP. I've got everything setup and I can access the web interface. I am getting the following error in my log:

disk_total_space returned false. Verify the web account user has access to /dev/shm

I saw somewhere that setting PrivateTmp=true to PrivateTmp=false in the Apache service file could fix that, but the person that proposed that got scolded for not understanding the risks of doing so. Is there a way to fix this error without compromising Apache?

FYI....I am running Arch Linux and ZoneMinder 1.30.4-1.

What does 'ls -ld /dev/shm' say?

'df | grep shm'?
