Request notifications

Hello all!
When a get on "Edit Group Properties". Especifially when I change font or color font. I have an error on my log:

---

can't read "header_font": no such variable
while executing
"set header_font "$community_header_font,$header_font""
invoked from within
"if { $community_id ne "" } {

"uplevel {

if { [file exists $__adp_stub.tcl] } {

....

So. What I did: Edit packages/theme-zen/lib/lrn-master.tcl on line 119:

from: set header_font "$community_header_font,$header_font"

To: set header_font "$community_header_font"

The problem was eliminated but any change to fonts aren't applied and there were more awfull errors when I tried of create a new group or communty.

I Hope You can helpme. What happen whit this header fonts stuff?

Thanks in advance!
