I have been banging my head against the wall with a phpbb upgrade on a Centos 7 box.
The install from phpbb did tell me that cache and several other directories could not be written to so I had to adjust the permissions.

That's easy so I chmoded the folders to 777 and I still got that message. I chomed in Cli and in Thunar and listed with ls-l and a lot of other stuff and clearly the permissions were given,
But phpbb3 kept telling me that it did not have write permission.

The phpbb forum had nothing on it either; they keep telling people to chmod to 777 - but that won't help. The situation I had was that everything was chmoded to 777 and still there were no write permissions.

Ahhh oh joy; at least my copy of this forum worked.
The update went through and I could turn SElinux back on again (as in "enforcing") after the upgrade.

It is also possible to leave SElinux on and make temporary changes for the files that need permission:
