[rt-users] Mason Cache clear

[Dunbar, Brian]

I was installing RT-Extension-ActivityReports into RT 4.4.0 after the install I ran 
rm -rf /opt/rt4/var/mason_data/obj
then service apache2 restart

Apache restarted ok but RT will not load. I found this error in syslog but not sure what to fix.
[40707] mkdir /opt/rt4/var/mason_data/obj/3407077840: Permission denied at /usr/share/perl5/HTML/Mason/Compiler/ToObject.pm line 115.#012#012Stack:#012

Then I google clearing mason cache and it shows 
rm -Rf /usr/local/rt4/var/mason_data/obj/*
Not usre if the asterisk at end makes difference I tried that after still no luck.

Anyone see what is wrong and how to fix?  Greatly appreciated.
